I have e2fsck in my rom, but I can't run it from a normal shell as the filesystems are already mounted. Is there a way to make a rom automatically check and repair the filesystems on boot, and if so, how can I control the options it passes to fsck? Are there other ways to get to an unmounted system or data partition? Does clockworkmod have any kind of shell or fsck utilities built in? Are there other recovery programs that may have something like that?
