How to maintain a few heterogeneous ubuntu boxes synchronized?

Asked by Stefano on 2010-04-01

I have a little pool of heterogeneous computers with Ubuntu 9.10 mounted and located in different places (home, work,...).
I would like to have the same set of (non-default) applications installed locally on each of them. Does it exist a way to maintain a list of needed applications and sync all the computers against it?

Take from ubottu's !clone message on freenode (assumes that all the programs in question are available from the default Ubuntu repository):

To replicate your packages selection on another machine (or restore it if re-installing), you can type « aptitude --display-format '%p' search '?installed!?automatic' > ~/my-packages », move the file "my-packages" to the other machine, and there type « sudo xargs aptitude --schedule-only install < my-packages ; sudo aptitude install » - See also !automate

Good luck,
