Reason for closing:  Not a bug
Additional comments about closing:  mpd-git install file renamed it, not pacman
Comment by Allan McRae (Allan) - Monday, 09 July 2012, 09:07 GMT
My analysis of the issue:
1) /etc/foo exists in the filesystem - not owned by any package
2) pkg1 is replaced by pkg2
3) pkg2 has /etc/foo in its backup array.

Should be easy to write a pactest for. Step #2 is the critical part.

I have no dea why this is moved to .pacsave rather than .pacorig and how no output about the move gets outputted...
