I played with Linux on SPARC once to test the portability of some
software I wrote.
I found various issues with whatever distribution I used (can't recall
which) with multi-threaded programs. Linux on SPARC is not well
supported, I don't think there is much (if any) development going on, so
I suspect Linux will be more hassle than it is worth.
I'm not sure of the best version of Solaris for a SPARC 5. I know
Solaris 9 will run, but it *might* be better to use an older version due
to it being more lightweight.
