I thought that we were pretty much universally mounting with an selinux
context, rather than allowing selinux to add its own on-disk attrs.

Why is that not the case for this test?

Works for me on this old kernel anyway:

[root@bp-05 xfstests]# getenforce
Enforcing
[root@bp-05 xfstests]# ./check generic/062
FSTYP         -- xfs (non-debug)
PLATFORM      -- Linux/x86_64 bp-05 2.6.32
MKFS_OPTIONS  -- -f -bsize=4096 /dev/sdc2
MOUNT_OPTIONS -- -o context=system_u:object_r:nfs_t:s0 /dev/sdc2 /mnt/scratch

generic/062 60s ... 3s
Ran: generic/062
Passed all 1 tests

Note the mount options above...
