>Description:
Did a portupgrade -af last recently.
After that squid and uucp didn't work anymore.
Reason:
I keep my uucp and squid configuration in different filesystems.

/usr/local/squid -> /data/squid (which is on a different disk
for better throughput)

/usr/local/etc/uucp -> /etc/uucp (because important config files
are easier for me to handle under one place under /etc and because
I'm used to have the real UUCP config files there.

portupgrade or whatever tool in the upgrade chain fails here
should honour symlinks correctly. Maybe somewhere a -f for
follow option is missing, or the tools should not only check
for the existance of a directory but the existence of a symlink
as well...

I think more, that -f or such is needed, since keeping a symlink
pointing to a non-existing directory also would be wrong IMHO.

At least its a bad thing as it is.
Regarding getting mail via uucp
its a bad think to do a portupgrade -a
and then seeing, that you are not getting any mail from
your UUCP feed.

It irritated me a bit since some mail came in via fetchmail ...

So it was not easy to see, what happend.

But it was not fine to see, that portupgrade does something nasty
and does not honour symlinks.
>How-To-Repeat:
Install squid.
then:
cd /usr/local
mv squid /data
ln -s /data/squid /usr/local/squid

Install freebsd-uucp
then
cd /usr/local/etc
mv uucp /etc
ln -s /etc/uucp /usr/local/etc/uucp
