had some good advice on when to use RAID on SWAP devices (it is a RAID 1 
in my case)

dirceted me to the man pages of mdadm which I will study in the near future.

Thank you for your advice, I lost track of the thread, didn't expect 
some further hints.

mdadm --monitor --test --scan
Showed me that no mail transfer agent is configured on the system:
sh: /usr/sbin/sendmail: not found
It should be quite obvious that a mail transfer agent need to be up and 
running but I cannot remember the alternate installer telling me to set 
up one. I remember the option to enter an email address to which error 
reports will be sent. I know that including the set up of postfix in the 
installer does not make sense but an advice to do this later on would be 
good. I will check the current ubuntu releases on this issue.
