[Pkg-utopia-maintainers] Bug#431101: dbus: init script fails with confusing message when /proc is not mounted

[Frédéric Brière]

Package: dbus
Version: 1.1.1-3
Severity: normal

In trying to build, within a chrooted lenny, a C# package that
indirectly build-deps on dbus, I stumbled upon this:

  Setting up dbus (1.1.1-1) ...
  Starting system message bus: dbusCould not tell if SELinux is enabled: No such file or directory
  SELinux pre-initialization failed
  invoke-rc.d: initscript dbus, action "start" failed.
  dpkg: error processing dbus (--configure):
   subprocess post-installation script returned error exit status 1


Turns out that dbus is looking into /proc as a last resort (which was
not mounted within the chroot), and this error message is merely the
ENOENT of the last attempt:

  13396 open("/etc/selinux/config", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
  13396 statfs64("/selinux", 84, 0xbfc498a0) = -1 ENOENT (No such file or directory)
  13396 open("/proc/mounts", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
  13396 open("/proc/filesystems", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
  13396 write(2, "Could not tell if SELinux is ena"..., 64) = 64


It would be nice if dbus could either survive when /proc is not mounted
(as it did in etch), or failing that, if it could issue an error message
to that effect.
