I would love to rearrange pacman's UI and merge -S and -U into
a generic install operation. I haven't worked on it in a while, but
I would like to see something like this:
The problem with allowing -S to handle paths/urls is that package
package names are also valid paths. Having pacman attempt to pick the
one that makes the most sense by default would be okay, but users need
to have some way to unambiguously distinguish between the two.
I don't think that just hoping that package names never overlap with
local files is enough.
For reference, you can see how pacinstall distinguishes the two here:
