The problem is that to boot a modern system, you need a shitload of stuff. For example, modern network filesystems often have secure authentication and probably LDAP too, so that means we need to move ldap and openssl into / and all the dependencies. Also, anything that installs a udev rule needs to be in /, and the list goes on an on. Very soon, you have almost everything in /... This rule made sense in the 80s, but it doesn't match the modern world anymore. Some longer explanations: http://www.freedesktop.org/wiki/Software/systemd/separate-usr-is-broken https://fedoraproject.org/wiki/Features/UsrMove Here is a list of packages on your system that will break if you start udev without /usr mounted: egrep 'usb-db|pci-db|FROM_DATABASE|/usr' /*/udev/rules.d/* |cut -f 1 -d : | sort -u | xargs qfile -e -- Olivier Crête tes...@gentoo.org Gentoo Developer
