           Summary: initrd fails to fsck root filesystem
           Product: System software
           Version: 3.2
          Platform: All
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Low
         Component: startup-shutdown
        AssignedTo: kimmo.hamalainen at nokia.com
        ReportedBy: jheather at zoo.co.uk
         QAContact: startup-shutdown-bugs at maemo.org


EXPECTED OUTCOME:
Add fsck of root filesystem prior to chroot to it
ACTUAL OUTCOME:

STEPS TO REPRODUCE THE PROBLEM:
Set to boot from external mmc. Boot then remove card - leaving filesystem with
repairable minor inconsistencies. Then boot of the card again.
OTHER COMMENTS:
I must say it is pleasing that the N800 needs none of the shennanigens that
(apparently) the N770 needed to boot off the mmc.
Simply setting the persistant boot device in the config area of the flash
allows a .ext2 formatted mmc to be booted. (I think maybe I should point
this out on the forums etc)



HOWEVER, the initrd linuxrc SHOULD NOT pass operation over to the filesystem
without running fsck -p on it. Failure to do so will happily turn a minor
inconsistency into major filesystem corruption. No doubt the code was written
with the jffs2 filesystem in mind, where it it unnecessary. Really you should
follow the usual linux practice of mounting the unchecked root readonly so you
can get at the right fsck and then remounting readwrite (after a reboot if any
problems are fixed) only when fsck -p returns with no problems. Oh, yes, and
drop into a shell if there are still unfixed problems after the first go.
