i am new to arch. i want to use latest mesa & i believe it can be installed using mesa-git.
the issue for me right now i have mesa installed on system.
pacmanXG shows the following mesa packages installed :
the issues are :
 do i need 1st remove all the above mesa packages before installing mesa-git ?
 can i install mesa-git first & then remove mesa ? which one is the best option  or  ?
 does installation of mesa-git will pull all of the above packages from aur ?
 do i need to configure anything extra, for example pacman, etc.
thanks for your time & patience.
