[HOWTO] ROOT=/path/ removepkg package

Post#1 by **Rava** » 22 Dec 2022, 23:47

Since some of the posts have been more about module extration, removepkg and such, I removed these from the original thread about fulalas Porteus review into here.
It started with parts of my own review of fulalas review:

Porteus 5 review (Post by Rava #92249)

Important:
If you do not exactly know what you are doing you can break your system, e.g. when you remove important parts of a core module and replace these with incompatible parts.
Please only do so when you have some knowledge about a Linux system. This is not recommended for new users fresh from Windows as their first attempt in creating an own module.

Only the parts relevant to ROOT=/path/ removepkg package I copy in here:

When asked, I would even recommend the user to patch her/his 002-xtra.xzm to make a 002-xtra_sans_celluloid.xzm out of that.
(And the user learns about the ROOT= hack in combination with removepkg, e.g.
Code: Select all
ROOT=/path/to/extracted/002-xtra_sans_celluloid/ removepkg celluloid
Not that it makes the module much smaller, but removing an application one really really dislikes entirely is something very… satisfying calming. )

Sadly, I cannot just move Testuser's post Porteus 5 review (Post by Testuser #92263) in here since it is older than my initial post above and the order of the posts would be messed up, therefore I quote his (her?) post instead:

I also never liked celluloid.

I tried ROOT=/path/to/extracted/002-xtra_sans_celluloid/ removepkg celluloid, but modules does not got smaller and only less files were removed

Also, can we make vlc player as default in Porteus becoz, when I tested vlc uses less resources compared to mpv for same video file.

Has anyone tested which video player uses least CPU?

The above line is just one part of a multi-step-process.

Let me create a "002-xtra_sans_celluloid.xzm" module out of the most recent 002-xtra.xzm so that you can see all the steps:

First extract the original, either use the RAM file system - or when that s not large enough to hold the extracted module and the creation of the new altered one, use a hard disk partition with an ext[234] partition instead.

1. Step: Creating the target directory, Extraction of the original module:
I copied the downloaded via /opt/porteus-scripts/update-porteus module "002-xtra.xzm" into its folder "/mnt/sdb4/bin/linux/porteus/5.0/x86-64/updates_core/20221212/" :
