Unfortunately I don't have the full debug logs yet, so I'll leave this to
Mike.

The package includes all upstream patches released so far (ie, up to
autofs-5.0.5-fix-submount-shutdown-wait.patch), minus the following ones:
autofs-5.0.4 - use intr option as hosts mount default (configuration change)
autofs-5.0.5 - add dump maps option (recent feature)
autofs-5.0.5 - add external bind method (recent feature)
autofs-5.0.5 - fix ext4 fsck at mount (no ext4 on SLES 10)
Thanks,
Leonardo
