You don't state an exact error message, so it's hard to say what went wrong. I'm guessing that either the root fs wasn't mounted rw, or you tried to edit the file in place instead of replacing it, and the daemon was still running at that point. Personally, I'd replace the file atomically from a copy.

Code:

# mntroot rw
# /etc/init.d/powerd stop

# cd /mnt/us
/mnt/us# cp /usr/bin/powerd powerd-backup # just to be safe
/mnt/us# cp /usr/bin/powerd powerd-modified
# edit powerd-modified

/mnt/us# mv powerd-modified /usr/bin/powerd #replaces the file atomically, even if the daemon were still running
# /etc/init.d/powerd start
# mntroot ro
