Subject: [PATCH] Remove setup_X_sockets(): The creation of Unix sockets
 directories in /tmp for X happens right after pruning /tmp. So the whole
 dance of checking for their existence, ownership or permissions is not
 necessary. It's safe to just create them with the right permissions if X is
 installed.

Changes to do_fsck():
Remove the _flags variable and pass flags to fsck directly with "$@".
