i've been experimenting switching back and forth between 2 different boot environments on a laptop: the original install was of snv_52 which was then lu-copied to the other lu env. i then upgraded the second env to snv_54. i have both env's set up as 10GB UFS partitons and i had a few ZFS partitions that i shared between the two. this seemed to cause lots of trouble due to the fact i think that config files and libraries are different between the two versions. i know i couldn't even launch gnome until i erased all the . files from my home directory-- some incompatibility between JDS 2.14 and 2.16. also all the gnu stuff i build in /usr/local on one env wouldn't run on the other env because of library troubles. i was sharing /opt withhout any trouble except for the different versions of star office, but that wasn't a big problem.
so my question is how do experienced users set up their partitions to not have toooo much duplicate data, but enough that one doesn't run into the problems i've described above? i thought about enlarging the UFS env partitions, but that seems a bit wasteful. but maybe that's the only way to keep the two env's isolated enough. thoughts??
