Push debs
I build myth on a backend server, then push it to the two front ends that I have. This process is a bit annoying. Here is a simple script that helps. Make sure that you:
1) can ssh into each frontend without having to type a password (authorized keys)
2) make sure that the user on each front end can sudo without password dpkg and reboot
FRONTENDS=(mythfe@192.168.1.101 mythfe@192.168.1.103) # Frontend # We --force-architecture during installation of debs because one # of the frontends is a AMD64 and we are building 32 bits # # This script should run without prompt if the users have sudo # access without password (see sudo visudo). index=0 element_count=${#FRONTENDS[@]} while [ "$index" -lt "$element_count" ] do current=${FRONTENDS[$index]} echo "=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-" echo "Pushing debs to "$current ssh $current rm -f *deb scp myth_src/mythtv-trunk/mythtv/myth*.deb $current:~/ scp myth_src/mythtv-trunk/mythplugins/mythplugins*.deb $current:~/ echo "Installing debs to "$current ssh $current sudo dpkg -i --force-architecture *.deb ssh $current sudo reboot echo "Rebooting "$current ((index++)) done echo "All done."
Note, that now I just use NFS and stop pushing debs arounds. :-)

Errors and Fixes
Sometimes one of the databases will get corrupt. This might cause all sorts of issues. One such issues may be that fast-forwarding and rewinding will not work cleanly. Instead of jumping to the next spot in a video, it will get suck on a screen that says "Searching...". If you see that, do this:
mysqlcheck --auto-repair -A -u mythtv -p
