Upgrading OpenBSD (merging /etc)

I just want to be sure about the files I should backup before copying etc31.tgz.

- /etc/passwd
- /etc/master.passwd
- /etc/pwd.db
- /etc/fstab
- /etc/myname
- /etc/mygate
- /etc/resolv.conf
- /etc/rc*
- /etc/newsyslog.conf
- /etc/syslog.conf
- /etc/sudoers
- /etc/group
- /var/www/htconf/httpd.conf

Then copy them back, except for the rc* in which case I will just reedit the newly copied files (since they change so much).

Did I forget anything?

I'm sure you've already done this but if not make sure to grab

/etc/hosts

and

/var/named

if your running DNS

Looks good!
