I did a freebsd to freebsd installation via ftp using PLIP for
3.0-970114-SNAP and I found filling out the networking menu where you enter
your IP data etc. slightly confusing.
I knew what my ifconfig command had to be but I couldn't guess where the IP
number of the other end had to go when filling out the menu. It didn't
seem to belong in the "other switches" box. In the end, I fudged it by
making my "other switches" section contain a ';' followed by what I wanted
my ifconfig command to be.
This may or may not make sense: could the networking menus have an extra
box where you can enter the remote host's IP address if you are using
point-to-point network links such as PLIP (and perhaps PPP too). It would
be best not to show the box if there was no remote host IP value to enter
(or we'll probably just confuse some other punters).
