Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

doesn't work with upstart. use
touch /forcefsckCan't use "touch /forcefsck". Root file system is mounted read-only due to disk problems. Cannot write to /. Cannot "mount -o remount,rw /" either.

at grub boot screen, hit 'a', append 'init=/bin/sh', after booting into shell you should be able to do the fsck, or do the remount and touch /forcefsck
also try single user mode (just append '1')
