Item 147. Set up LVM on Server. (Holiday Job).

Item 148. Convert /var/spool/cyrus partition on server from ext3 to
reiserfs for performance gains. (Holiday Job).

Thanks Craig. ;-)

Seriously this is only my home server so it is not critical (only 3
users) and it is more of a "how can I do it better" kind of scenario
than a "pressing need" situation. That said my wife's Outlook baulks
sometimes with Cyrus (not sure if it is Cyrus or Outlook, probably the
latter) and my PLUG archive is quite big and takes sometime to search. 

Thanks for the info though. Should come in useful when I have the time
to do it.
