[mythtv-users] How to backup progs before upgrade?

[Cliff Avey]

I've downloaded the mythtv 0.20.2 tarball and I'm building it now. 
Everything is going smoothly as described. I've made a backup of my 
mythconverg db. However, before I su and run make install, I'd like to 
make a backup of my working old version (0.18). I've got scheduled 
recordings almost every evening. If something goes wrong it would be 
nice to be able revert to the old version until I can figure it out.

I installed 0.18 from packages using the Mythtvology guide. Looks like 
most everything is installed is /usr/bin. If I make a backup of 
/usr/bin/myth*, will that back up everything that would get replaced by 
running make install on v0.20? Or are there other programs in /usr/bin 
or elsewhere, or config files anywhere that I should save before 
installing 0.20?
