In the end I got "aklog" to work. This is how I did, If anyone should

This command took some time to finish. (I didn't have module-assistant
installed, so I did "sudo aptitude install module-assistant" to obtain
This one was really quick.

What does this do? Is it always run at boot? Or do I need to see to it
that it is?

# sudo /etc/init.d/openafs-client start
Starting AFS services: afsd.
afsd: ERROR: Cache dir check failed (cannot use reiserfs as cache partition)
Found the following advice on http://www.debian-administration.org/articles/610.
"The cache directory must be on an Ext2 or Ext3 filesystem partition.
In case it is, you just have to ensure there's enough disk space on
"In case it is not, in case you're using a different filesystem for
/var/ or /var/cache/, then you need to mount an Ext partition or file
onto /var/cache/openafs/. "
So I created a 600 MB loopback file using (loopback stuff gotten from
# dd if=/dev/zero of=/ytra/openafs-cache.loopback bs=1024 count=600000
600000+0 records in
600000+0 records out
614400000 bytes (614 MB) copied, 30.3648 s, 20.2 MB/s
Set it up as loopback device:
# sudo losetup /dev/loop0 /ytra/openafs-cache.loopback
Formatted the device with ext3 file system:
# sudo mkfs.ext3 /dev/loop0
mke2fs 1.41.3 (12-Oct-2008)
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
37520 inodes, 150000 blocks
7500 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=155189248
5 block groups
32768 blocks per group, 32768 fragments per group
7504 inodes per group
Superblock backups stored on blocks:
Writing inode tables: done
Creating journal (4096 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 25 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
And then mount the thingy as the openafs cache directory:
# sudo mount /dev/loop0 /var/cache/openafs/
This worked, so I stopped openafs-client, unmounted everything and
added my loopback device to /etc/fstab so that everything would work
after a reboot.
# sudo /etc/init.d/openafs-client stop
# sudo umount /var/cache/openafs
# sudo losetup -d /dev/loop0
Added to /etc/fstab:
/ytra/openafs-cache.loopback /var/cache/openafs ext3 loop 0 2
Now the loopback will be mounted on boot, and can be mounted with:
# sudo mount /var/cache/openafs
And my /etc/rc.* directories seem to include openafs-client. So I'm
guessing everything will start okay (and I'm in no mood to do the
actual reboot, so that'll have to do for now).
"klist -T" ("-T, --tokens display AFS tokens" according to the
manpage) now says:
