Comment # 2 on bug 1029961 from Daniel Molkentin

Quoting the linked text:

"/bin contains commands that may be used by both the system administrator and
by users, but which are required when no other filesystems are mounted (e.g. in
single user mode)."

With systemd, the notion of /usr potentially not being available is over. It
has to be part of the root file system, or in a filesystem that can be mounted
simultaniously. In that sense, we already obsoleted that part of FHS 3.0
implicitly by moving to systemd.

We do not have to do symlinks and do like Fedora does, i.e. symlinking /bin to
/usr/bin. However, dimstar pointed out that this could cause problems with
legacy packages. that install a file to /bin while another package has the same
file in /usr/bin.

Either way, having _some_ base system packages in /bin and not others is not
helping the cause. And IMHO, there is neither a good point nor a feasible way
in re-introducing /bin, nor would it have a real purpose. Please help me out if
I am missing something essential here (other than adhering to an already
implicitly obsoleted standard).
