[linux-lvm] Modifying lvmcreate_initrd

[Holger Rauch <Holger Rauch heitec de>]

Hi!

I've modified "lvmcreate_initrd" in such a way that it can be used to
build a customizable rescue system. Instead of taking the files to be
copied to the RAM disk from a variable, as the present
"lvmcreate_initrd" does, I'm gathering this information from several
files:

- binary_files_for_initrd: contains assorted binaries from /bin, /sbin,
/usr/bin, and /usr/sbin
- config_files_for_initrd: the desired config files from the /etc dir
- auxiliary_files_for_initrd: contains additional files that don't fit in
any of the above categories, e.g. everything under /usr/lib/terminfo
- symlinks_for_initrd: contains the name of the symlink and the file/dir
the link points to.

Each of this file contains one entry per line. Those entries may also
contain wildcards, e.g. "/etc/lvm*". Comments start with a "#".

The problem I'm currently having with this approach, however, is that when
booting from LILO, a "Loading rescue......................" message is
displayed on the screen. Then my machine hangs (normally it should
simply boot the kernel at that point). What can be the cause of
this behavior?

All the work is done by "main.sh" (a rather unfortunate name, I admit it).
"constants" contains some constants which are needed inside "main.sh".
"glob_vars" holds all the global variables, and "functions" has all
function declaration, some of which are not used yet.

One of the main differences (apart from the fact that it doesn't work
yet (-, ) from the present "lvmcreate_initrd" script is that it uses a
file along with a loop device associated with it in order to hold the RAM
disk's contents (the present "lvmcreate_initrd" uses the RAM disk straight
ahead and this would take too much RAM by far for what I'm trying to
achieve).

The system I'm using for this is a SuSE 6.4 system (glibc 2.1.1
based) with reiserfs 3.5.18 and lvm 0.8e.

The reason why I'm actually changing the "lvmcreate_initrd" script is that
I want a rescue system that can live in "/boot" independently of the
remaining file systems on the hard disk. This would be particularly useful
when switching distributions and yet wanting to preserve existing logical
volumes. Please tell me what you think of this idea.
 
Any help is greatly appreciated!

Greetings,

	Holger
