l-m-c & hwpack fails / tries to rm /proc

[Tom Gall]

Using l-m-c from today (9/20)

./linaro-media-create --rootfs ext3 --mmc /dev/sdc --dev beagle --hwpack /home/tgall/hwpacks/hwpack_linaro-omap3_20100917-16_armel_supported.tar.gz --binary ~tgall/binary-tar-alip-0918.tar.gz

I see...
sudo sfdisk -l:
Disk /dev/sda: 19457 cylinders, 255 heads, 63 sectors/track
Disk /dev/sdb: 481 cylinders, 255 heads, 63 sectors/track
Disk /dev/sdc: 966 cylinders, 255 heads, 63 sectors/track

mount:
/dev/sda1 on / type ext4 (rw,errors=remount-ro,commit=0)

Are you 100% sure, on selecting [/dev/sdc] (y/n)? y

There's a much longer list of proc/* entries following but no other messages from l-m-c besides of the form "trying to rm something in tmp/tmp.Ljq8n0b7bQ/binary/proc/*******': Operation not permitted

Granted the error about broken packages is there, but the point of this bug report is we probably should fail a little more gracefully.

[Guilherme Salgado (salgado)]

This happens because when the call to linaro-hwpack-install fails, l-m-c will try to remove the temp chroot without first unmounting its /proc

[Guilherme Salgado (salgado)]

Tom, can you try l-m-c from lp:~salgado/linaro-image-tools/bug-643601 and see if it fixes this problem?

[Tom Gall (tom-gall)]

Shall do! Thanks!

[Martin Pitt (pitti)]

Accepted linaro-image-tools into maverick-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

This bug was fixed in the package linaro-image-tools - 0.3

---------------
linaro-image-tools (0.3) maverick-proposed; urgency=low

  [ Steve Langasek ]
  * no longer using the 'omap' uboot flavor support in live-helper; instead,
    run the mkimage commands directly for omap.
  * fix the paths used for looking up x-loader and u-boot binaries in the
    tarball; these don't belong in /boot at all, pull them from /usr/lib.
  * only enforce the presence of commands we're actually using; this lets
    us automatically pull in btrfs-tools when btrfs is specified.
  * add sudo to a couple more commands in linaro-media-create, so the script
    itself can run as non-root as intended.

  [ James Westby ]
  * Add a linaro-hwpack-create script for the creation of hardware packs.

  [ Steve Langasek ]
  * Fix lookup of linaro-hwpack-install to work correctly when l-m-c is on
    the path. Closes: #652669.

  [ Loïc Minier ]
  * Drop spurious single quote character in boot_args_options for beagle|igep;
    thanks Peter Maydell; LP: #667400.
  * Set LC_ALL=C when entering the chroot as it has no locales. LP: #651905.

  [ Tom Gall ]
  * Use --numeric-owner argument to tar when unpacking, so that files get
    the right owner on boot of the image. LP: #652121.

  [ Dave Martin ]
  * Implement proper cleanup handling on signal / exit, so that we don't
    leave clutter behind on error. This also fixes the message at the end of
    a successful install about being unable to unmount proc. LP: #616385,
    #660196, #667394, #643601, #627383.

The new version of linaro-image-tools (0.3) works for the vexpress platform.

[Steve Langasek (vorlon)]

Thanks for confirming. Since this l-i-t works for all of my image creation tests, and has now been independently verified, I'm marking this bug as verification-done.
