Hello everyone, I've got some exciting news :) /bin/sh runs!!!
Things start up all the way -- exec, proc, auth, all that. Then /hurd/startup exec's /libexec/console-run; I placed a little shell script there. The shell (dash) starts up, loads the script, and starts executing it! And (this required another tweak to TLS) it manages to fork and exec a command! The command being "settrans -ac /dev/mach-console /hurd/streamio console" -- and that seems to (mostly?) succeed too, streamio starts up and settrans does call file-set-trans on the ext2fs. But I haven't yet been able to receive any actual output from the shell or subsequent commands on the console. But -- we now have enough of Unix working to fork and to run /bin/sh! How cool is that?! Patches coming some time soon (tm). Sergey
