Does Slackware support UNIONFS?

#1 (**permalink**) 02-20-2008, 09:23 AM

I am trying to mount a Knoppix computer under NFS.
This used to be no problem but Knoppix has gone to the UNIONFS
filesystem in the latest version.

When Knoppix is mounted at / I I can see directories that look like:
etc -> /UNIONFS/etc
but they are not readable.

Does Slackware support UNIONFS at all?
Has there been any mention of support in future versions?

There were no hits under Google using 'slackware unionfs' search term
except for some Slax stuff. Nothing in the changelog. Nothing in
/usr/src/linux/.config.

Using Slackware 10.1 with the 2.4.29 kernel.

Seems the Linux kernel does not support it(as far as I can find in the
kernel config file), so you would have to find whatever 3rd party
module Knoppix and Slax use.

In addition, you can find an article in Linux Journal (December 2004
issue) titled "Unionfs: Bringing File Systems Together." It is available
online at:

compiled without hassle for my own 2.4.31

Checkout http://www.linuxlive.or

At this point unionfs isn't available natively in the kernel. Yo
need to download the source and compile it for your kernel

Unionfs allows you to mount multiple filesystems on top of each other
which is very handy for live cds
