Thank you for the hints about running a system with a shared /usr. The
point I was trying to make is that there is no ready-made, easy tool
available for maintaining such a setup - the way that using
dselect+dpkg make it easy to maintain the installation on a single
machine. Here, some comercial UN*Xes provide more tools than the ones
I'm aware of in the public domain. Even though I can get put together
a flexible setup using PD tools, the initial effort required tends to
put off system administrators.
Having said so much, I am actually rather interested in exchanging
ideas on how to ease the maintenance of a cluster of Debian
machines. Having three machines to look after, I'm starting to think
about maintenance scripts...
Cheers,
Lukas
