And much harder for people who have already decided to play around with
/bin as a symlink. This all broke me pretty hard because I tried to upgrade
glibc by itself (I necessarily needed a different package which doesn't
have "duplicate" ldconfig files in it). My own fault, of course, but it
should be noted that anyone else could potentially run into this if glibc
isn't upgraded at the same time as the filesystem package.
Oh well, at least I'll be home tonight to fix it.
