rootcopy vss from_iso

New features which should be implemented in Porteus; suggestions are welcome. All questions or problems with testing releases (alpha, beta, or rc) should go in their relevant thread here, rather than the Bug Reports section.

rootcopy vss from_iso

Post#1 by lo-n-behold » 16 Mar 2011, 12:36

when using the from_iso cheatcode, i.e. booting from a ISO file on usb,
it's impossible to put files inside the ISO for copying onto the root filesystem.

I would like to use the following layout on my removable media:

Code: Select all

would it be possible to support this in the default linuxrc ?

I think this small patch implements this, in a compatible way with the existing code.

Code: Select all

thanks for sharing your code (i see that you have read linuxrc carefully - well done!), but i find it too static as /rootcopy must be placed in same folder as the porteus.iso

what about more flexible solution: 'rootcopy=' cheatcode?
it could be placed on another device, folder, etc like:
with full path: 'rootcopy=/dev/sda3/porteus/rootcopy'
with relative path: 'rootcopy=/porteus/rootcopy'
or even
with completely different name: 'rootcopy=/mylinux_stuff/porteus-v.1.0-rootcopy'

if no 'rootcopy' cheatcode is specified then standard $PTH/rootcopy/ would be used.
i dont think many people will use it but implementing it shouldn't be too hard for me :)

BTW: linuxrc development should be discussed in this thread:
Please add [Solved] to your thread title if the solution was found.
