The best answer is for someone to look into udev and see what it needs exactly from /usr. Does it really need pci.ids? Or is it just the fact that random udev rules might rely on a tool/lib in /usr? Former, yes, pci.ids is perfectly valid to go into /etc. It specifies a mapping of PCI ID numbers to device strings used in udev rules. In the latter case, maybe rules specifically required for booting up enough to mount disks need to be isolated into their own file and udev pointed there, then re-pointed to the bigger file after /usr is made available. If that is even possible. Note: I'm brainstorming here. Anyone else?

Yes, but some of us don't even want to have that initramfs built into our kernels. And no one, other than freedesktop.org* and a few people on linux-hotplug-devel*, said everything belongs in /usr. FHS clearly defines the roles for /, /bin, /sbin, /lib*, /usr, /var, /home, /tmp and the virtual fses. Plus others. http://www.freedesktop.org/wiki/Software/systemd/separate-usr-is-broken http://marc.info/?l=linux-hotplug&m=131206447302056&w=2 Really, MacOS's filesystem layout is not something anyone in their right mind should deign to mimic/copy. -- Joshua Kinard Gentoo/MIPS kumba@g.o 4096R/D25D95E3 2011-03-28 "The past tempts us, the present confuses us, the future frightens us.
