gpt device node does not show at boot

[Rong-en Fan]

I'm running 6.2-RC1 on i386. I use gpt(8) to partition my
disk. After reboot, the device node, say da1p1, does not
show up until 'gpt show da1' is issued. This prevents
gpt partition being mounted from fstab, and therefore
cannot be nfs exported at boot time!

My kernel config is simply GENERIC+QUOTA+SMP.

I also noticed that it is not possible to modify in-use
disk's partition table. There is also a PR 85772 about
it. Can someone comment on it? Thanks.
