[lsb-discuss] No separate /usr anymore?

many users/sysadmins are alarmed by the messages of the systemd init
as systemd does complain that /usr as a separate partition isn't
supported anymore[1,2,3,4].

The real reason seems not related to systemd nor to sysvinit but
to udev[5] which does not support a separate /usr anymore.  The
background seems to be that there is no check for utilities belonging
to the /usr partition.  As the udev utility is a major part of most
modern distribution today and moving all required tools from /usr to
/ will become /usr useless as this may require also moving a lot of
libraries and other binaries (e.g. for resolving the dependencies
for the tools and libraries for bluetooth support).

Now the question rises if LSB/FHS will be changed at this point?
