So even putting /var on the hard disk would not help much?

I did think of that but that does not resolve all the problems - it
allows me to create a new (virtual) server quickly and swap it in when
it is ready to go - so there is not much downtime BUT then the
underlying OS doesn't get updated . . and I still have the same problem
to update that. I have been thinking about using a SSD for the OS but
it would be nice to be able to plug in a new drive without taking the
box apart - I suppose I could look for plug-n-play SSD that can be
inserted into a drive-socket in a standard CD drive bay . .


USB sticks are not fast enough. However, you might find that an SSD in a
portable case *with eSATA* will be fast enough not to be objectionable.
Set things to boot from the external (in BIOS) and test it. When ready,
halt the server, swap the SSD into the box and reboot, change the BIOS,
and done!. Downtime maybe 4 minutes if you are quick. Data can be on
another physical drive, or replicated to a partition on the
to-be-swapped drive immediately before server shutdown.


I have a portable external drive case which cost maybe $8 more for eSATA
capabilities and it IS fast. Waaayyyy faster than USB!
