[Debian-ha-maintainers] Bug#577965: fails to install when user ais already exists

[Thorsten Glaser]

Package: corosync
Version: 1.2.0-3
Severity: important

The file corosync.postinst contains:
	adduser --quiet --group --system --no-create-home ais

This, however, fails with error code 1 if the user ais already
exists on the system, so the package fails to configure.

(Reason: I have backported lvm from sid, with the OpenAIS hack¹
applied, and all its dependencies to lenny for my dayjob by re-
quest of a colleague.)
