Subject: please support boot without aufs
Date: Thu, 30 Sep 2010 10:56:18 +1300
Package: initramfs-tools
Version: 0.98.4

aufs is an out-of-tree project, and this presents considerable
management challenges.  For instance, current the Linux kernel in
experimental has no aufs module.

Given that compared to tmpfs, aufs is used primarily to save RAM, it
should be reasonable to fall back on tmpfs for creating writable
filesystem spaces during boot.

If I were to come up with a patch to the various scripts which support
graceful fallback to tmpfs, would it be possible to include it ?

Cheers,
Sam.

I don't know what makes you think initramfs-tools uses aufs, but it
doesn't.

initramfs-tools doesn't care about aufs at all, do you mean
live-initramfs/live-boot instead?

You're right, I was fooled by the file existing
in /usr/share/initramfs-tools/scripts, sorry to bother you...

for >2.6.32, we are aiming for uionmount support. yesterday, Michal
provided a patch for initial support of that. have a look at
git://live.debian.net/git/live-boot.git.

if neither aufs nor unionmount (nor unionfs-fuse; which is not really
supported well anyway) is present, a tmpfs fallback would be indeed
nice, yes.

sure.

Eventually, live-boot will support additional stuff (it's on our todo
page at http://live.debian.net/devel/live-boot/todo), but since these
are wishlist items open for long time, requireing quite a bit of work to
implement and nobody worked on them for years, I do not see much point
in keeping it rotting in the bts, that's what we have the todo page for
(that includes above things, and much more).
