Hi guys, I have been thinking about sorting out /usr being a separate mountpoint. Mainly because I keep getting bug reports that turn out to be caused by this. The current status is that we move some tools from /usr to / in the hope that this will allow us to boot without /usr being mounted. This mostly works, but not quite, as there are still stuff left in /usr that are used by early boot (and mostly just fails silently). This website created by the systemd folks sums it up nicely (just replace "systemd" with "initscripts" everywhere): <http://www.freedesktop.org/wiki/Software/systemd/separate-usr-is-broken>. The solution they propose, and which I agree with, is to mount /usr from the initrd just as we mount / (an alternative solution is to just declare separate /usr as not supported, but I guess that would not make us popular). Before working up a patch, I wanted to hear if there are any objections to this approach, and in particular that Thomas agrees that it is the right way to go. The interface I suggest is to allow two new kernel options "usr" and "rootflags" that correspond to "root" and "rootflags". The pivot_root stuff I submitted recently will already take care of unmounting. The syntax could obviously be discussed, and I suggest getting in touch with the dracut guys to make sure we choose the same syntax (I don't think they yet have support for this, but I might be wrong). Any thoughts? Cheers, Tom PS A nice sideeffect is that once we have this we can simplify a lot of our PKGBUILDS as they never need to put stuff in / any more, and eventually /bin, /sbin and /lib will be empty and can just be symlinked to /usr/{{,s}bin,lib}.
