/tmp/<blar>/proc is not cleaned up correctly on error

[Lee Jones]

On error l-m-c seems to try to delete the /proc filesystem it created.

This results in 1000's of these:

What version of l-m-c were you running when this happened? This issue
(bug 660196) was fixed recently.

[Peter Maydell (pmaydell)]

Bug 660196 claims this bug was fixed in linaro-image-tools 0.3; however I still see it in 0.4.3-0ubuntu2.

[Guilherme Salgado (salgado)]

Can you reproduce it reliably?

This used to happen when interrupting the script (Ctrl-C) during the
hwpack installation, but I can't seem to reproduce it here using trunk.

[Peter Maydell (pmaydell)]

Yes, it's 100% reproducible -- just hit ctrl-c at the apt-get prompt:

(or alternatively, type 'n' and then hit ^C afterwards while l-m-c is cleaning up.)

[Guilherme Salgado (salgado)]

That bug was actually fixed after 0.4.3; I commented there and will get
someone with the necessary rights to change the state of the tasks
there.
