[ale] Reboot wedging problems after disk transplant

[Dow Hurst]

A big fat UPS with nut running on the server for autoshutdown on low 
battery and you won't have this problem ever.

This also indicates that even though you are using a journaling 
filesystem the meta data doesn't seem to be written to the journal 
immediately and is being lost.  There may be a parameter for ext3 that 
says don't wait to write metadata.  XFS always writes metadata 
immediately in the SGI implementation.  You can lose real data still in 
RAM but at least the file system integrity won't be compromised.  A UPS 
based shutdown normally just runs the "shutdown -h now" command, so 
flushes data to disk.  The journal should always be uptodate anyway.
