[PATCH] Basic root filesystem maintenance module

[PATCH] Basic root filesystem maintenance module

[Yanko Kaneti]

Just the other day I rebooted with rdbreak with the idea to shrink the
root fs a little, only to find that none of the fack/resize/tune tools
for ext3 were actually in the initramfs. Here is a first attempt at a
basic dracut module that includes those. Worked in brief testing.

Not really attached to the patch itself, but I would like to have a way
to include those basic tools one way or the other.

Cheers
Yanko

Not a bad idea! Just a thought: Why not just add these to the debug module?

As far as I understand its off by default which would have also foiled
my initial uninformed attempt at resizing. I kinda expected a generic
initrd to have some basic fs maintenance tools.
