Replacing a package without reinstalling dependencies

I have gotten a new Nvidia card and want to stop using Mesa. When I try "pacman -S nvidia-libgl", I get
:: nvidia-libgl and mesa-libgl are in conflict (libgl). Remove mesa-libgl? [y/N] y
error: failed to prepare transaction (could not satisfy dependencies)
:: glamor-egl: requires mesa-libgl

Trying to remove mesa-libgl tells me that about 4GB of packages will be removed. I have them in the package cache, but it would take forever to reinstall them.
Should I just do a manual installation, overwriting mesa-libgl, or play it safe and remove mesa-libgl, install nvidia-libgl, and reinstall all my packages?

man pacman

Look under the 'transaction options' header.

Re: Replacing a package without reinstalling dependencies

Both nvidia-libgl and mesa-libgl provide libgl. Removing (and reinstalling) all packages depending on libgl is indeed a waste of time, but with conflicts/provides pacman should handle that just fine. Packages that explicitly require mesa-libgl will have to be removed (or replaced) anyway, so why don't you start by removing glamor-egl and trying again.
