Hi all,
I have several machines running FBSD now. At the moment I have a complete ports tree on each machine. I was wondering if it was possible to have it all on just one machine and NFS mount it?
That is certainly possible.
I have already been doing this for the /usr/ports/distfiles directory, but had not shared everything else as I was not sure if settings from a build on one machine may cause problems when building on another machine.
Each machine has it's own /etc/make.conf with settings such as the processor type, so it is important that one build can't effect another.
I would suggest you set WRKDIRPREFIX in /etc/make.conf so that the files built by the ports system do not get placed under /usr/ports but somewhere else.
Is it just the object (.o) files that this effects, or all generated files? Where do the configurations get saved (for those ports with a config menu)?
For example I have 'WRKDIRPREFIX=/var/workdir' in my /etc/make.conf. That way all the files that are created when you build a port ends up under /var/workdir rather than under /usr/ports. If WRKDIRPREFIX is set to a directory on a local filesystem there will be no way for a build on one system to affect one on another. You should even be able to export /usr/ports as read-only.
If it was read-only, where would the source files that usually go into /usr/ports/distfiles go? I'd like to only have to download these once too.
(Changing WKRDIRPREFIX also makes it a lot easier and faster to clean up after building ports. Instead of having to issue a 'make clean' for each port built, you can just do a 'rm -fr /var/workdir/*' and all the workdirs will be removed quickly.)
I usually do a 'make install clean' anyway, but it would be good to be able to verify everything is actually cleaned.
The other advantage of all this of course is that I would only need to do CVSup once and every machine would be up to date.
Thanks for the help, Rich
