Perhaps at some point, the keydisk will contain items like voicemail, 
extra sounds, etc.  Password changes, user additions etc might go on a 
unionfs partition.

The unionfs stuff will be in flux for a period of time.  It has not been 
decided if the keydisk will remain permanently or if a unionfs partition 
will replace it.

The revision number is in /etc/astlinux-release.  In a "released" 
version, this would be the release number.  In a build from SVN, this 
will be the SVN number (for example, astlinux-trunk-1361).

A script does exist called genunion.  It's a bash script which can be 
found in /usr/sbin.  It will create a filesystem which can then be 
specified as a boot argument.  ASTURW=/dev/part# or ASTURW=auto.  If 
using auto, the partition intended for use as the unionfs writable 
partition must be labeled as ASTURW.

There are a few quirks that we're looking into.  It works right now in 
many cases.  It has not been tested in all cases (specifically in low 
memory situations).  I've changed the password for the root user and 
that is retained on future boots on the unionfs partition.  There is an 
odd issue that I haven't been able to solve at the moment.  Any kernel 
modules that are loaded are copied to the unionfs partition.

There's been some documentation on using unionfs on the Astlinux web 
page (under documentation).
