[pacman-dev] Bug with remove conflicting packages and their depends

[Allan McRae]

[2014-08-21 21:27] [PACMAN] Running 'pacman -Syu vim-minimal'
...
[2014-08-22 09:17] [ALPM] removed vim (7.4.404-1)
..
[2014-08-22 09:17] [ALPM] upgraded vim-runtime (7.4.404-1 -> 7.4.410-1)
[2014-08-22 09:17] [ALPM] installed vim-minimal (7.4.410-1)
...
[2014-08-22 09:17] [ALPM] installed ruby (2.1.2-1)
[2014-08-22 09:17] [ALPM] installed lua (5.2.3-1)


Ruby and lua are dependencies of vim which is removed.  They were
orphans after this transaction.


Here is debug output:

:: vim-minimal and vim are in conflict. Remove vim? [y/N]


So I guess the fix is to consider explicitly stated packages first.

I'll file a bug report later.
