Since Edgy, Ubuntu requires the use of '''UUID''' or '''LABEL''' (for filesystems including swap), or udev-created symlinks (for removable media like CDROMs and USB drives). Directly using {{{/dev/hd*}}} or {{{/dev/sd*}}} is no longer supported (since these device assignments can change from boot to boot): * all filesystems should be specified by {{{UUID=}}} or {{{LABEL=}}} * all physical devices should be specified by a symlink (e.g. {{{/dev/cdrom}}}, {{{/dev/disk/by-id/...}}}, etc.) The files for which this is most critical are: * {{{/boot/grub/menu.lst}}} * {{{/etc/fstab}}} * {{{/etc/initramfs-tools/conf.d/resume}}} To perform these renamings (which should have already happened during the Dapper to Edgy upgrade) please use: * {{{/boot/grub/menu.lst}}}: {{{ sudo /usr/sbin/update-grub }}} * {{{/etc/fstab}}}: {{{ sudo rm -f /etc/fstab.pre-uuid sudo /var/lib/dpkg/info/volumeid.postinst configure }}} * {{{/etc/initramfs-tools/conf.d/resume}}}: * Verify that {{{RESUME=}}} matches your {{{swap}}} line in {{{/etc/fstab}}} * After any adjustment, run {{{sudo update-initramfs -u}}} |
