I am running a P4 desktop and a centrino notebook with Debian sid and
I wanted to know what the best way is to keep the same set of packages
installed on both machines.  For the initial setup of the laptop, can
I install a base system and then rsync /usr and /var/lib/dpkg from the
desktop, or is there a different way that is better?
# on your desktop:
dpkg --get-selections > my-selections.txt
# copy my-selections.txt to your laptop

# on your laptop:
dpkg --set-selections < my-selections.txt
apt-get dselect-upgrade

Useful to know...

I assume that any modifications to the /etc/apt/sources.list file would
need to be copied across to the target system before the upgrade?

I wonder what complications could arise if the two machines are running
different versions of Debian - I am thinking of my i86 Etch install
on my notebook vs the ARM system on my iPAQ.


I run amd64 and i386 ports with apt-cacher. It just means that any packages that are architecture independent (*all.deb) only need to be downloaded once. Others will have to be downloaded for each machine.

You may run into trouble if a package is available in one arch but not another when trying the dpkg --set-selections step above.
