Yup!

Boot into single user mode before doing this,
or, better yet, `shutdown' from multiuser.
This will save your mounts in read-write.

Here is my layout:

# df /var /usr
Filesystem  1K-blocks     Used    Avail Capacity  Mounted on
/dev/da0s1e     29727    16715    10634    61%    /var
/dev/da0s1f   2956432  1746143   973775    64%    /usr

# ls -l /var/mail
lrwxr-xr-x  1 root  wheel  9 Jun 10  1998 /var/mail -> /usr/mail
