Well, the problem I'm seeing on a machine with NFS home directories and 
LDAP authentication is that after the network is brought down calls by 
pm-utils to sync hang (presumably NFS related) and I see lots of 
nss_ldap cannont connect to LDAP server errors and the hibernate process 
hangs.

I suppose I should file a bug - against pm-utils for incorrect ordering 
of scripts?  Should I expect this to work?
