Hi Uli:
Thanks again.   There was an email from Mathew Seaman - however it came as
only attachments, and not knowing him I did not open them - there was not
text at all in the body of the email.
Maybe I will now open it..
I read my emails with pine (a console mail client) on my FreeBSD 
system - no chance for Windows virii.

I do not know anything much about inodes or file handles either... My
thinking was to just use brute force and chop away much of the ports
collection that I am not likely to need on my little web server.
Too true,
you would need
- apache (and if you like mod_php and mysql ???)
- midnight commander (mc) for file management
- a console browser (links or lynx) for quick checks.
Still I would recommend binary upgrades, these programs don't 
need any special compile time options. But that's your fun.

Uli.

I don't want to put everything into too much of a tizzy however the next
time I update them.  Probably the most sensible thing to do is simply remove
it entirely and just do single port upgrades as needs be.
Cheers,  Graham/

Hi Uli and the rest of the FreeBSD forum:
Thanks for your advice - though I am not entirely sure what the purpose
of
your last questions are.
I wanted to know about your ressources, since your ports dirctory
might grow very big, if you don't clean it up every now and then.
Matthew gave some hints about that at the last part of his mail.
I hardly know anything about inodes, but as far as I understand,
you would have to reformat your entire filesystem to change
anything about this.
The simpliest way to update your system on a small hd
would be to keep strictly to binary upgrades and installations.
You won't need the ports directory then (neither the system
sources in /usr/src).
Another simple idea would be to get another small hd somewhere,
devide it into two slices and mount one on /usr/ports and the
other on /usr/src .
This would give you enough space to do full rebuilds of your
system and your ports.
If you have enough patience and time you can also download single
port directories from www.freebsd.org/ports, place them in
appropriate directories and try to make install them.
They will complain when they are missing some other port.
I have done that to set up a samba printer server, but next time
I will use binary packages.
Uli.


To answer though:
My HD is about 1.2G - it is sharing 2.0G with another OS.
/usr    ~ 778M
usr/ports ~247M
total /usr being used is ~595M  with about 183M free.
The problem is not disk space - it appears to be file handles.
Remember,
those ports files are only about 0.5K each - so lots of inodes are being
used in file infrastructure.  Midnight Comm which I use for a lot of
file
navigation indicates that I had 99838 inodes available - of which there
are
now only 602 free!   Yesterday that was about 900, but then I mirrored
part
of a friend's website and used another 300.
As you can see, I need to free up some file handling capability.
Thanks for any further advice you can give.
Cheers,  Graham/

Is it alright to prune the Ports tree - and still do updates later.
I am running 4.8 stable and recently did a full Ports tree
update using CVSUP.  This generates several questions. 1) I
took the advice of Michael Urban's book and upgraded from the
"Head" of the source tree rather than from that for 4.8 - did I
really want to do that?  Does it matter for a Ports only
updating?
It is recommended to use the appropriate kernel and base system
with your ports. Things might work the way you did it, or
(probably) not.
2) The tree is getting pretty big - result, lots of
files.  My hard drive is not very big - it is down to a few
hundred inodes (file handles) within the usr directory.  Can I
prune the tree on my hard drive without compromising future
updates?  If it helps, my machine is not using X only command
mode so there are lots of Ports that will never be made.
For further advices it would be helpful to know how big your hd
is and how much diskspace is used by your ports tree.
You can check the latter by
# du -h -d 1
(see # man du)
Regards,
Uli.
Thanks for any help that can be offered.
