Either solution's preferable to my first inelegant attempt at an rc.tmp
involving making a complete pigs' ear of rc!  :)

I used the same procedure, but with the size set to 1G (on i386) I kept
getting some sort of overrun problem with newfs; I wasn't able to track
down the cause to either newfs or disklabel, but creating a separate "a"
partition seems to have done the trick in my case.  Unfortunately I can't
say for certain if that fixes the problem or merely avoids it.

Cheers,

Chris.
