Summary: Debian SSIFailover uses findfs, but...

Initial Comment:
findfs looks in /etc/blkid.tab, which doesn't seem to be a cdsl, so it finds the same device on all nodes.  Rather a problem if two nodes have different names for the same device (can happen for example on shared SCSI).

# onall /sbin/findfs UUID=b7c7645c-1d6f-4943-88c0-269ec640f5d3
(node 1)
/dev/sdc1
(node 2)
/dev/sdc1

# onall sh -c 'blkid -c /dev/null  | grep b7c7645c-1d6f-4943-88c0-269ec640f5d3'
(node 1)
/dev/sda1: LABEL="/root" UUID="b7c7645c-1d6f-4943-88c0-269ec640f5d3" SEC_TYPE="ext3" TYPE="ext2"
(node 2)
/dev/sdc1: LABEL="/root" UUID="b7c7645c-1d6f-4943-88c0-269ec640f5d3" SEC_TYPE="ext3" TYPE="ext2"

Need "mklocalfile /etc/blkid.tab"

Problem is blkid_flush_cache function writes temporary then uses rename to
move it into place.

Doesn't quite work - apparently someone rm's blkid.tab on boot.

Also, should be running blkid on boot or nodeup?
