pkgin uses "pkg_add -f"

[gdt]

I had xentools41 installed, and did "pkgin in xentools24". This should have failed, because xentools42 conflicts with xentools41 because PLISTs overlap. pkg_add rejects this addition. As a result, I had a mix of the packages, and when I removed xentools42 the xentools41 package was broken. It seems this happens because -f is pased to pkg_add.

This is a critical integrity failure; it should not be possible to reach unsafe states with pkgin. pkgin should never use -f with pkg_add. I really do mean never; if some specific check needs overriding for a good reason, there should be a flag to just skip that. (Arguably, pkg_add/etc. should have a coherent scheme of named checks with a flexible override mechanism.)

pkgin has been modified in order to use pkg_add -D instead, could you try it and tell us if it behaves as expected?
