:Yes, but unless you've built all the ports, you won't even come close
:to hitting that limit. There are 4200 ports, which is below the
:limit as far as counts go (which is 8192, iirc). You might hit the
:64k total arg length limit.

:When I have a boatload of ports to delete, I use something like:
: find /usr/ports -name work -type d -prune | xargs rm -rf
:so that I don't exec too many times, but yet I don't overflow the
:argument size limits.

Since I export /usr/ports read-only, I never put my work directories
in the ports hierarchy itself. I set /etc/make.conf to:
WRKDIRPREFIX= /var/tmp
Or something similar, then simply 'rm -rf /var/tmp/usr' when it gets
full or I want to clean it out. (I have a big /var/tmp to accomodate it,
but there is nothing preventing you from creating a directory in /usr
to hold the workdirs either).
