screen transcript follows: >> Determining root device... >> Mounting /dev/vg_main/swap as root... >> Using mount -t auto -o ro !! The filesystem mounted at /dev/mapper/vg_main-swap does not appear to be a valid /, try again !! Could not find the root block device in . Please specify another value or: press Enter for the same, type "shell" for a shell, or "q" to skip... root blick device() :: /dev/vg_main/system Reproducible: Always Steps to Reproduce: Try booting into an "invalid" root block device, then pick a valid one. Actual Results: leftover mount from initrd: /dev/mapper/vg_main-swap /newroot ext4 ro,relatime,data=ordered 0 0 # umount /dev/mapper/vg_main-swap umount: /dev/mapper/vg_main-swap: not mounted Expected Results: There be no leftover mounts Can the "does not appear to be a valid /" be changed into something more informative? PS: I don't know what version of genkernel created that initramfs, but it was after kernel 3.8.6-hardened was stabilised.
