The problem is, that you don't really =20 know if the installation is just to create a package, or if the user =20 also wants to use the port after the installation (I create a package =20 after each update of a port).

Right, but if you want to install e.g. the acroread port, linux_base =20 and linux-gtk2 will be required. linux-gtk2 not only installs libs, it =20 also has to run a linux program to register some gtk plugins. There's =20 more to this than just not running ldconfig. > You need linux.ko installed to run linux ldconfig which some > linux ports do if they install linux shared libs. > > Kostik is requesting a [non-default] way to tell the ports > infrastructure not to die if I want to install a linux port without > linux.ko loaded. > > There were some concerns expressed about just warning if ldconfig > doesn't get run because that would leave the ldconfig cache possibly > set incorrectly. > > My point is that even if the linux ldconfig's cache is not right on a > port install, it will be corrected the next time /etc/rc.d/abi is run > (to that end, it's better than manually running 'sudo kldload linux'). > > So let's say you are installing a port to a chroot on removable media > that is intended to be installed on another box - a useful mode of > operation I hope you agree.

And if the linux-gtk2 port is installed, a lot of stuff will just not work. I don't say it is not possible to do, I just say it is not as easy to =20 get right as most people think.
