[buildd-tools-devel] Bug#567932: schroot: chroot failed, cleaned up my host /etc

[Hamish Moffatt]

Package: schroot
Version: 1.4.0-1
Severity: critical
Justification: causes serious data loss

I upgraded schroot from 1.2.3-1+b1 to 1.4.0-1, which wanted to replace
some config files, which I have customised. I declined, intending to fix
it later.

I started an schroot into an old sid 32-bit chroot (from my sid 64-bit
host), and didn't notice any error messages, but found I was still
running 64-bit binaries. I think the actual chroot() failed.

Later after exitting, I found that a bunch of files in /etc were now
empty: passwd, group, shadow, hosts, protocols, services.
