By far the easiest way to deal with this without having to predict if maybe /usr is mounted or not, or if maybe your intiramfs has the correct files in place and all sorts of other maybes, is the following: - find any old LiveCD/installer/whatever on CD or thumb drive (the gentoo minimal install CD works just fine, so does ubuntu-server installer (it boots quite quickly) - set your BIOS to boot from that device - reboot - use the fsck tool on that system (which is independent of your main system) to fix the broken fs for /usr - reboot as normal Yes, you *could* fiddle with your initramfs to provide a shell and fs tools. How often are you going to use it or test it? As you are not RedHat with paying customers, I'd say "almost never". so rescue disk ftw -- Alan McKinnon alan.mckin...@gmail.com
