Changing macports install directory *after* installing?

Yes, it is possible to maintain a single MacPorts opt directory on two machines and have one installation outside of opt if they are both running the same version of OSX and XCode. The quick and dirty way that I do the same task on my own machines is.

Yes, it is possible to maintain a single MacPorts /opt directory on two machines and have one installation outside of /opt, if they are both running the same version of OSX and XCode. The quick and dirty way that I do the same task on my own machines is: rsync -arvz $macports_host_machine:/opt/ /Volumes/extradrive/opt/ where $macports_host_machine is the machine on which MacPorts is installed (in /opt/). Now, link /Volumes/extradrive/opt to /opt: sudo ln -s /Volumes/extradrive/opt/ /opt/ I also perform this additional step sudo chown -h username:group /opt sudo chmod -h 755 /opt to change ownership and permissions of the symbolic link.

After that, I maintain the /opt directory on only $macports_host_machine and rsync with all of my other machines (running the same version of OSX and XCode) periodically. The previous instructions were written assuming that MacPorts was installed in /opt on $macports_host_machine, if MacPorts was installed in some other non-standard location, you should replace /opt with whatever the installation path is on $macports_host_machine.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
