At which point(s) during the build?

For sbuild:

During any command run as the build user (*not* root), it will
default to

    my %common_keys = (
        'PATH'                                  => {
            DEFAULT => "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
        },

(from Sbuild::ConfBase).  They should be present when running commands
as root, though I'd have to double-check that.

It looks like we currently pass SHELL through, unless you configure it
otherwise.  Maybe this should be revisited?

I think that this is correct (as the default behaviour; it could be
configured otherwise).
