* dependancies, I think it would be a nice idea to add an option to
* pkg_delete to automatically delete all dependancies that aren't currently
* used by anything else. If nobody is interested in doing this, I can do it
Be careful about that "aren't currently used by anything else" part.
If you already had a port A installed, and then later installed B
(which just happens to depend on A), you could get A erased when you
erase B.
You probably need to change pkg_add too, so that it will note
somewhere on A's dependency list that it was installed by which port,
and let pkg_delete check it.
It usually goes like this:
@ install B, pkg_add installs A too, and mark A that it was
"installed by B"
@ deinstall B, pkg_delete checks A, finds the mark and deletes it too
While, if you had installed A beforehand, it will be like:
@ install A
(...few months pass...)
@ install B, nothing special happens re the flag
@ deinstall B, pkg_delete checks A and doesn't find the flag, so
doesn't delete it
You can also add a flag to pkg_delete to override said check in case
you know you installed A just for the purpose of installing B.
If you come up with the file format and patches to pkg_*, I'll modify
bsd.port.mk so it will DTRT on dependencies installed by "make
install".
