I've been upgrading a few computers and I want to say that it did show up in M11.

Looking here: ftp://ftp.mepis.com/mepis/pool/main/a/aufs/ , I only see aufs-modules-2.6.* packages for earlier Mepis releases.

It doesn't look to me that Warren has added aufs support to Mepis 11.0 yet.

There are updated aufs-modules-2.6.32-1-mepis* packages with yesterday's date (2/24/11). Those updates are for M8.5.

If aufs support were to be implemented in Mepis 11.0 in the same manner as it was done in earlier releases, I would expect to see some aufs-modules-2.6.36-1-mepis* packages in Warren's repo.

I apologize for my ignorance, but I was under the impression that aufs was only useful on a Live CD/DVD and not an installed system. :confused:

For aufs to work in the live DVD the kernel needs to be patched, which it has not been at this moment in time.

It can have its use on an installed system: "A union mount is a mount that allows several filesystems to be mounted at one time, appearing to be one filesystem." For example I use aufs in the remastering script. Instead of copying the entire unpacked ISO (takes time and lots space) I just mount it with aufs.

@joany,
In Mepis 7.0, 8.0 & 8.5 the aufs-modules-2.6.* package was preinstalled and I assume that that is what made the aufs mode possible for LiveCD/DVD sessions. I don't know what if any use 'aufs' can be used for on an installed system.
edit: I see Adrian does have some potential uses for 'aufs' on an actual install.

@Danum,
If the kernel gets patched, is a aufs-modules-2.6.* package still needed as it was with earlier Mepis releases?

The main problem as I remember is that there are no patches, or modules, which you need for the kernel Mepis is using.
Added the fact that most linux-distro's have moved on from using aufs, debian live is a good example.
This is from the introduction @
http://aufs.sourceforge.net/
Note: it becomes clear that "Aufs was rejected. Let's give it up."
According to Christoph Hellwig, linux rejects all union-type filesystems
but UnionMount.

As of today, there are only two "aufs" packages in M11: aufs-tools and aufs-tools-dbg. In M8.5 there are about 20 packages, notably an array of aufs-modules packages, which I believe are necessary to get aufs working.

As much as I would love to see aufs enabled in the M11 Live DVD -- it's a wonderful way to run MEPIS through its paces on real hardware without installing it -- I'm not very hopeful that aufs will make it into the final.

If they've moved on from using aufs, are they using something else that provides the same type of capabilities in a Live session that aufs offers?
