When I have this issue, my main concerns are:

- a new version may require changes in config or rc files and that could 
ruin old versions

- a new version may overwrite component/footprint library files that may 
break existing designs

- a new version may have library dependencies that are incompatible with 
an old version


For the first two a different installation path (prefix) is enough. When I 
hit the 3rd, I use chroot.

My generic (not limited to geda) approach is that I have a semi-stable 
host system which typically lags 0.5 .. 2  years behind latest stuff. 
Then I have (or can easily set up) chroot with the 
latest-hottest-unstable stuff and I usually have a chroot with a much 
older system for cases when I need to revive bitrotten code.

There's a minor hassle with chroot regarding to X, but that's easy to 
solve and I usually put it in a shell script that wraps chroot.

Regards,


Igor2
