to be honest, i knew it could be done because i had heard rumor that blaketh had done it earlier. his patch wasn't immediately available, and it seemed like it should be simple, so i redid it on my own. but yes, the fact that OFW stays resident, and stays useable (to the extent that your OFW commandline history is preserved across invocations!) even after the OS has started is the really wonderful part. paul =--------------------- paul fox, [email protected] _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
