I have not seen code so I can only guess. I hate to be a bother here, but aren't there some legal concerns with looking at Solaris source code, then implementing code in Linux? Even on OpenSolaris, there is a grey area as to whether one can legally view CDDL licensed code, then reimplement it as GPL (CDDL is GPL-Incompatible) for Linux... but on old Solaris, that code should be proprietary, unless Sun opened it when I wasn't looking. Mark, can you legally be doing this? ~spot
