Package: live-boot
Version: 4.0.2-1
Severity: wishlist
Tags: patch
Dear Maintainer,
There are a few features I have come to love in other live systems that are not
available in the current live-boot system. I have attached a patch that adds
these features and think it maybe valuable upstream.
1. rootcopy: This allows for one or more folders on the boot medium that
contain a folder structure relative to /. before init, these files are copied
to the rootfs. This feature allows users to make small changes to their
environment (like wallpaper changes or dekstop icons) without needing to
remaster or have a persistent volume.
2. modularized filesystems: This allows for the use of a file, *.module, that
contains newlibe seperated squashfs filenames to be loaded in order. This is a
change from the default behavior of coping all squashfs files and mounting them
in alphabetical order.
3. packge installer: This allows for a user to include a small apt repo in the
live media. By creating a *.package file, a user can tell the system to
install these packages from the repo on boot before init. This is helpful for
testing packages without having to remaster.
I have been using these for quite some time and found them to be critical in my
use. I would like inclusion upstream so I don't have to continually patch as
new versions are released.
