[Pbuilder-maint] Bug#439285: pbuilder login does not create a login shell

[Ben Hutchings]

Package: pbuilder
Version: 0.161
Severity: normal

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

pbuilder login does:

	${CHROOTEXEC} bin/bash

This starts bash as a normal interactive shell, not a login shell.
This means that it can, for example, be suspended, with unpleasant
results.  bash's exec command allows setting the invoked program's 0th
argument with the -a option, so it would be possible to start a login
shell with:

        (${CHROOTEXEC} bin/bash -c 'exec -a -bash bin/bash')
