I have OpenBSD, FreeBSD, and Red Hat 6 (government wanted some software run and guess who gets the $) running in my server room.
Red Hat seems to be fine with yum, and I haven't had a problem yet. FreeBSD's pkg (pkg-ng technically) is ok, but I keep running into problems on upgrading because someone split a pkg or renamed it. I search but don't find a simple solution. I haven't had any problem on the OpenBSD side, but that could be because every 6 months do an upgrade with the new release. Patches are a bit harder on OpenBSD unless freebsd-update does something weird. the whole src thing in the freebsd-update bit me.
