Re: [PATCH v14 0/2] CPIO & OVA Images

[Henning Schild <henning.schild@siemens.com>]

I just read some logs where three wic images are created in the same
chroot.

The first one failed to umount tmp

> umount: /builds/.../build/tmp: target is busy.

Followed by the other two not being able to find wic_fakeroot.

I guess we will have to see how to react on mount/umount issues to make
them fail ... and not some follow-up.

And roughly looking at the code i guess we will have to grab a
buildchroot lock in do_wic_image. In fact i guess the locking of the
buildchroot should probably be implemented inside buildchroot_do_mounts.
