My personal view is that it is best to have it not mounted usually, but
I always create a fixed directory for it and have a "noauto" entry
for it in /etc/fstab.

For most of my machines the current name is /ofw (but I plan to change it
to /boot if this proposal makes it in).

This setup has a few advantages:

 - tools / scripts / my dim memory can use a fixed dir to make it available
   for bootloader updates

 - the exact device mounted varies a lot and, this provides a fixed
   place to encode that information (in /etc/fstab)

 - during normal operation, it is very hard to damage your boot setup
   (this point is quite weak and probably only a serious issue if you
   are careless as root and have a build setup for lots of different
   architectures and risk to overwrite the bootloader with a wrong
   architecture one or similar)

My typical /ofw partition also has an emergency "known working" kernel and
a matching extracted /rescue.
