stateless linux

[Peter Schobel]

ok, i guess what's happening is that it can't determine the snapshot
information - any idea why this might be?


[root at pinab-devel ~]# /etc/cron.hourly/stateless-replicator
Mounting /dev/hda3 at /tmp/tmpkI23Bo/reserve_root (type ext3)
Mounting /dev/hda1 at /tmp/tmpkI23Bo/reserve_boot (type ext3)
Could not determine client snapshot information for reserve boot

Probing devices to guess BIOS drives. This may take a long time.

   lists possible command completions.  Anywhere else TAB lists the
possible
   completions of a device/filename.]
