installboot fails - (un)safe to reboot?

[Jan Danielsson <jan.m.danielsson%gmail.com@localhost>]

Hello,

   I'm trying to remotely upgrade a NetBSD system, and I've encountered
a problem.

   I've built userland and kernel, and I've copied the new kernel in
place, I copied the new usr/mdec/boot to /boot, and I was going to
update the updated bootstrap code using:

   # installboot /dev/rsd0a /..buildpath../usr/mdec/bootxx_ffsv1

   But this fails with:
   installboot: Opening file system `/dev/rsd0a' read-write: Operation
not permitted

   Obviously I'd like to know why installboot fails, but more
importantly I'd like to know if it's safe to reboot in this state (/boot
updated, but installboot hasn't run)?
