Bug#410147: live-package: leaves debian-live/chroot/proc mounted on failure

[timo.lindfors at iki.fi (Timo Juhani Lindfors)]

Package: live-package
Version: 0.99.19-1
Severity: normal

I forgot to use --http-proxy and

time sudo make-live -d etch -p minimal -m http://apt-proxy.kurp.hut.fi:9999/debian/

failed with

The problem is that after this failure debian-live/chroot/proc is
still mounted preventing the user from simply doing "rm -fr
debian-live".

When I add "sh -x" before the command I see that the last two commands executed are

+ Chroot_exec 'apt-get update'
+ chroot /local/lindi/debian-live/chroot /usr/bin/env -i HOME=/root PATH=/usr/sbin:/usr/bin:/sbin:/bin TERM=screen ftp_proxy= http_proxy= DEBIAN_FRONTEND=noninteractive DEBIAN_PRIORITY=critical apt-get update

Shell doesn't seem to execute anything after chroot has failed since
"set -e" is in effect.

Please let me know if you can't reproduce this bug. I'm happy to
provide more info.
