(what a day i'm having... i just got it back and spent the day trying to find out why java would not run. after examing working- and non-working-strace's i noticed that the date was set to 1904. the java vm will not initialize with a date like that. maybe it's because sun realizes that no java machine was known to be working in the year 1904.) -- Brad brad@turbolinux.com http://www.turbolinux.com/~brad/ ** Sent via the linuxppc-dev mail list.
