When I don't set hook_ and backup_dir, a missing $HOME variable is
enough to stop notmuch.

When I set both config variables, notmuch does not care about a missing
$HOME.
I wonder why that is; both hook and backup dir are automatically
inside database.mail_root (or database.path) and don't need home at all.
