good point, after amending fstab and checking gpt labels carefully, it still
works ok for me:

root@a01 /u/h/dch# gpart show
=>      40  97677232  da0  GPT  (47G)
        40    532480    1  efi  (260M)
    532520      2008       - free -  (1.0M)
    534528   8388608    2  freebsd-swap  (4.0G)
   8923136  88754136    3  freebsd-zfs  (42G)

root@a01 /u/h/dch# grep swap /etc/fstab
/dev/gpt/swap0          none            swap    sw                      0       0

root@a01 /u/h/dch# swapinfo
Device          512-blocks     Used    Avail Capacity
/dev/gpt/swap0     8388608        0  8388608     0%

root@a01 /u/h/dch# sysrc dumpdev
dumpdev: AUTO

root@a01 /u/h/dch# dumpon -l
gpt/swap0


I do have these set in loader.conf, though, switching them off makes no difference:

root@a01 /u/h/dch# grep geom /boot/loader.conf
kern.geom.label.disk_ident.enable="0"
kern.geom.label.gptid.enable="0"

A+
