Bug#646829: installation failure - CD not mounted properly

[Steve McIntyre <steve@einval.com>]

Hi,

I've seen lots of recent reports of problems trying to install from
CD/DVD, and I've tried a test install to see what's going on.

When installing without network, grub-installer can't install the
grub-pc package that it needs. This appears to be because the CD is
not mounted inside /target. Talking to Colin on IRC, initially we
suspected commit 06493b627abc8636826fb22f7615635e9f90872d in
apt-setup, but later testing with that change backed out shows exactly
the same problem...
