[pacman] Provides and dependency tracking.

If I have a repo with package foo-git that provides foo, have package bar depends on foo, and no package foo, what will pacman do when trying to install bar? I have 3 variants:
1. Pacman will fail with cannot resolve dependences.
2. Pacman will install foo-git and bar.

What variant now, and what preferred?

If all is well, pacman will ask you which one to choose if there is more than one package providing the same thing. This is what happens when installing for example libgl.

Re: [pacman] Provides and dependency tracking.

Pacman will only do what runical describes if those alternatives are present in the SAME repo .

Basically when pacman checks for dependencies, it goes through every repo listed in pacman.conf but stops once it has found that dependency.

say foo is present in [extra] and foo-git in [rilian-la-te-repo] .

If [extra] is above [rilian-la-te-repo] , pacman will always find foo in [extra] and install that version.

If you prefer pacman to use your version, you will have to list [rilian-la-te-repo] ABOVE [extra] .

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
