compiler versions to a version that only exists in Redhat, so you need
to recompile all your binary packages. Discovering that they've moved
the directory of something, so that your files are no longer being
referenced. Discovering that they've deprecated something all together
so it's gone. I've ridden the waves when Redhat moves first. I
remember moving to Glibc (oops! Nothing compiles anymore!), and PAM
(Oops, forgot to clean up a lock file), or .... I eventually got
irritated enough to move. I'm always keen to hear of alternatives, or
if they have changed their ways enough to make me want to switch back.
