[SOLVED] Pendrive with Partitions [SOLVED]

Post#1 by inukaze » 06 Jul 2023, 08:11

Hi there, look the first is my native language is spanish, i am latino but not from "Europa Latina" like Spain, France, Italy, Portugal, Rumania, Moldavia, etc . . . well the thing is i had a pendrive with the follow partitions :

USB Pendrive with 14.43 GiB
Partition 1 : exFAT, 11.32 GiB, label : Inukaze
Partition 2 : ext2, 100 MB, label : Inicio (boot on spanish)
Partition 3 : ext3, 3.00 GiB, label GNU_con_Linux (GNU with Linux on spanish, because GNU is the OS and Linux is just the kernel)

i had installed grub from Slackware 14.2 on the Pendrive, and i write manully my own configuration file of grub.

When i boot my porteus from usb, search for it configuration file, and found on /mnt/isoloop
the thing is when this is booted the partition for grub is /dev/sda3, but when porteus found his configuration file and before the modules be loaded, the partition change from /dev/sda3 to for example /dev/sdc3

currently the blkid output of pendrive partition :

Code: Select all

/dev/sdc1: LABEL="Inukaze" UUID="38C0-FCD0" BLOCK_SIZE="512" TYPE="exfat" PARTUUID="29504791-01"
/dev/sdc2: LABEL="Inicio" UUID="a0784a07-12ba-4131-a646-726a70ad6a55" BLOCK_SIZE="1024" TYPE="ext2" PARTUUID="29504791-02"
/dev/sdc3: LABEL="GNU_con_Linux" UUID="23b2374a-ee65-49dc-9abd-562449624a68" BLOCK_SIZE="4096" TYPE="ext3" PARTUUID="29504791-03"
currently my grub.cfg content

i am using the entry "PRUEBA -- LXQT [REQ : 256 MB RAM]"
and well i just gonna to make some test like delete my workaround for change root variable value from example (hd0,msdos3) to sda3, i need a better command for mount the third partition no matter if sda3, sdc3, sdz3 for make porteus automount the folders i need to use.

just ignore the entries like "Cambiar Fondo" is just for chage image background, in some point i lost the entry i was make to change the font and save the change.
i just need ideas for had a better form to mount the third partition of usb after porteus found it config file but before try to mount the modules folders

Yes, Grub's partition names are different from Linux's.
If I understand your question correctly the regexp in the following grub.cfg snip should do the trick:

Code: Select all

set default=0
set timeout=10
set menu_color_normal=light-gray/blue
set menu_color_highlight=blue/light-gray
#set menu_color_normal=white/black
#set menu_color_highlight=black/light-gray

regexp --set=hdX '^(.*),' $root

menuentry 'Slackware 15.0 Current' {
   set root=($hdX,7)
   linux /boot/vmlinuz root=/dev/nvme0n1p7 ro pci=noaer
   initrd /boot/initrd.gz
}

menuentry 'Rescue' {
 # To run with less RAM add "boot=live" phrase - media will be in use
 # To override a saved keymap add a "keymap=<keymap>" phrase
 # To boot in text mode add a "consoleboot=yes" phrase
 # To start the network early at boot add a "networksetting=dhcp.eth0" phrase
 # To enable printing issue "/etc/init.d/cups start" in an xterm
   echo Loading ...
   set rescue=boot/rescue-5.10.7b.iso
   loopback loop /$rescue
   linux (loop)/pmagic/bzImage root=/dev/nvme0n1p5 loglevel=0 pci=noaer \
      directory=boot iso_filename=$rescue boot=live \
      cgmanager=no nfs=no bluetooth=no cups=no zfs=no atop=no \
      powermanager=yes
   initrd (loop)/pmagic/initrd.img (loop)/pmagic/fu.img (loop)/pmagic/m.img
}

menuentry '===' { true }

menuentry '[10] Xubuntu 23.04 "Lunar Lobster"' {
   set root=($hdX,10)
   linux /boot/vmlinuz root=/dev/nvme0n1p10 ro pci=noaer
   initrd /boot/initrd.gz
}
nvme0n1 is a nvme m.2 but the same setup should work for a multipartition USB stick.
:D

PS: I would go for the Grub from Slackware 15.0 or even better Current.

This is one of my nvme0 system's USB grub menus:

Code: Select all

menuentry " Porteus 5.0 USB - AF'" --class slackware   --class icon-porteus  {

     set porteus_parms="volume=33 reboot=cold extramod=/Modules changes=EXIT:/changes/porteussave.dat"

     set bootdrv=$root
     search -f /boot/syslinux/vmlinuz --set=root
     if [ $root != $bootdrv ]; then
        linux  /boot/syslinux/vmlinuz $porteus_parms
        initrd /boot/syslinux/initrd.xz
     else
        echo "----------------------------------------"
        echo USB drive NOT found.
        echo
        sleep -v -i 10
     fi
     set root=$bootdrv
     }
If you have Porteus installed on your harddrive adding a unique dummy file to the USB drive and searching for that instead of vmlinuz works also. :happy62:

Notes diferences with old version

grub.cfg, line 2
old

Code: Select all

set prefix=$(root)/grub
current

Code: Select all

set prefix=($root)/grub
grub.cfg, line 30
old

Code: Select all

set locale_dir=$(root)/locale
current

Code: Select all

set locale_dir=($root)/locale
with the old i see the follow error during grub boot :

Code: Select all

error: $
error: syntax error
error: incorrect command
error: syntax error
error: file /locale/es.mo.gz not found
and i just remove my workaround because is not really necesary

[SOLVED] Pendrive with Partitions [SOLVED]

Post#5 by inukaze » 16 Aug 2023, 17:03

Update 16 August 2023
-------------------------------

i had backup all content on a diferent hard drive, on 3 folders for make backups of each partition i had on pendrive
after i make all conent backup, i delete table patitions for pendrive and make new three partitions

Code: Select all

parted -l
Model: Verbatim STORE N GO (scsi)
Disk /dev/sdc: 15,5GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

Numero Inicio Fin Tamaño Typo Sistema de ficheros Banderas
1 1049kB 8349MB 8348MB primary ntfs
2 8349MB 8621MB 273MB primary ext2 arranque
3 8621MB 15,5GB 6868MB primary ext3

Code: Select all

fdisk -l /dev/sdc
Disco /dev/sdc: 14,43 GiB, 15489564672 bytes, 30253056 sectores
Modelo de disco: STORE N GO
Unidades: sectores de 1 * 512 = 512 bytes
Tamaño de sector (lógico/físico): 512 bytes / 512 bytes
Tamaño de E/S (mínimo/óptimo): 512 bytes / 512 bytes
Tipo de etiqueta de disco: dos
Identificador del disco: 0x2af862f0

Disposit. Inicio Comienzo Final Sectores Tamaño Id Tipo
/dev/sdc1 2048 16306175 16304128 7,8G 7 HPFS/NTFS/exFAT
/dev/sdc2 * 16306176 16838655 532480 260M 83 Linux
/dev/sdc3 16838656 30253055 13414400 6,4G 83 Linux
Notice i change the first partition from exfat to ntfs, just i can't format directly on exfat using gparted of Slackware64 14.2
on Slackware64 14.2 i try to use mkfs.exfat but the partition make unusable, and becuase of that i decide format on ntfs.

The first for me was copy boot partition data to my partition labeled "Inicio" (boot) after of that
first i must install grub on usb root device.

Code: Select all

grub-install --removable --recheck --boot-directory=/media/Inicio /dev/sdc
second i must edit the grub.cfg but first i must know which are the new uuid :

Code: Select all

blkid | grep sdc
/dev/sdc2: LABEL="Inicio" UUID="db288d5b-878e-46cb-a4ed-7003484981e2" BLOCK_SIZE="1024" TYPE="ext2" PARTUUID="2af862f0-02"
/dev/sdc3: LABEL="Lignux" UUID="187367fe-2cf8-4317-84fb-294bb88a877d" BLOCK_SIZE="4096" TYPE="ext3" PARTUUID="2af862f0-03"
/dev/sdc1: LABEL="Inukaze" BLOCK_SIZE="512" UUID="5C3D93A53E6C5477" TYPE="ntfs" PARTUUID="2af862f0-01"
well my current grub.cfg
The differences was
old "Inicio" uuid "a0784a07-12ba-4131-a646-726a70ad6a55"
was changed by "db288d5b-878e-46cb-a4ed-7003484981e2"
The new "Inicio" uuid

old "GNU_con_Linux" uuid "23b2374a-ee65-49dc-9abd-562449624a68"
was changed by "187367fe-2cf8-4317-84fb-294bb88a877d"
The new "Lignux" uuid

Because i lost symbolic links on the partition "Lignux" when i backup to another hdd and restore the data to pendrive partitions i must re-created them, but before

i had download the modules :

libuv -> http://ftp.osuosl.org/pub/slackware/sla ... 6_64-1.txz
bind -> http://ftp.osuosl.org/pub/slackware/sla ... ck15.0.txz

the bind module requiere libuv for work, i just convert both and activate first the libuv after bind, for i can use rndc without trouble

Code: Select all

cd "/mnt/sdc3/Porteus/Modulos"
ln -sf "../Modulos-xzm/Official/bind-9.16.42-x86_64-1_slack15.0.xzm"
ln -sf "../Modulos-xzm/Porteus/idioma-esp/es-core_locales.xzm"
ln -sf "../Modulos-xzm/Porteus/idioma-esp/es-lxqt_locales.xzm"
ln -sf "../Modulos-xzm/Porteus/idioma-esp/es_VE-locales-files.xzm"
ln -sf "../Modulos-xzm/Salix/exFAT/exfat-utils-1.3.0-x86_64-1salix15.0.xzm"
ln -sf "../Modulos-xzm/Official/exfatprogs-1.1.3-x86_64-1.xzm"
ln -sf "../Modulos-xzm/Salix/exFAT/fuse-exfat-1.3.0-x86_64-2salix15.0.xzm"
ln -sf "../Modulos-xzm/Porteus/idioma-esp/glibc-i18n-2.33-x86_64-5.xzm"
ln -sf "../Modulos-xzm/Official/gpm-1.20.7-x86_64-9.xzm"
ln -sf "../Modulos-xzm/Official/ntp-4.2.8p17-x86_64-1_slack15.0.xzm"
after of that i must update my /etc/rc.d/rc.local of Porteus partition Update of -> viewtopic.php?p=94894#p94894 and this include the solution for the problem i had with bind9 on ->viewtopic.php?p=95212#p95212

after i had activate libuv & bind i can create the named user & group

Code: Select all

su -c "groupadd named ; useradd -c "BIND Owner" -g named -s /bin/false -u 20 named ; install -d ; ldconfig" root
Ok going with my /etc/rc.d/rc.local :
Well i had 2 Games (and multiples emulators) on my "Lignux" partition, but i want re-create "Link" on "Desktop" every startup,becuase if i use on anothers pc's or if i connect more hdd, the pendrive should be moved from sdc to another sdX, i prefer make symbolic links to mount points using /media/"Label" for be more consistent.

well i had "Mupen64Plus" (N64 Emulator), "Tibia" (MMORPG Native), "Gravity Circuit" (Run & Gun Native)
for each i make a script called "Crear_Enlace.geb" ("GEB" = Guion En Bash, Spanish words, if i translate to english be "SIB" = Script In Bash)

Mupen64Plus - Crear_Enlace.geb
Tibia - Crear_Enlace.geb
Gravity Circuit - Crear_Enlace.geb
i need a script inside the home to use with autostart applications, i create a file "$HOME/.reparar-enlaces.sh" with the follow content
i make another file script "$HOME/.tumblerd-control.sh"
Well now the autostart apps :
and finally i must block a lot of suspices sites using /etc/hosts
my /etc/hosts file had the follow content :
