NetBSD netbsd60.domain_not_set.invalid 6.0 NetBSD 6.0 (GENERIC) i386
Architecture: i386

>Description:
A nfs mount pointing to the local machine causes quota_get() to fail.
quota_get() is working on remote nfs mounts.

>How-To-Repeat:
Turn on quotas for a filesystem.
Set quotas on a user.
Create a nfs mount pointing to the same machine.
Check the quotas for that user.
