Hi all,
With grub I usually use PARTUUID rather than UUID to specify the
location of my file system :
linux/boot/vmlinuz root=PARTUUID="7d896f5 ....."
It works very well. But recently I needed to use initrd (*) and I used
the script mkinitramfs described in the blfs-book chapter 5.
But then my system refused to start. The reason is that the init.in
script does not support the case of PARTUUID.
It is very easy to include this functionality in the script by simply
adding a single line in the function do_mount_root() :
do_mount_root()
{
mkdir /.root
[ -n "$rootflags" ] && rootflags="$rootflags,"
rootflags="$rootflags$ro"
case "$root" in
/dev/* ) device=$root ;;
UUID=* ) eval $root; device="/dev/disk/by-uuid/$UUID" ;;
PARTUUID=*) eval $root;
device="/dev/disk/by-partuuid/$PARTUUID" ;; <=== add this line
LABEL=* ) eval $root; device="/dev/disk/by-label/$LABEL" ;;
"" ) echo "No root device specified." ; problem ;;
esac
et voila!
a simple suggestion which could be included definitively in the script
hoping that it would be useful for others.

(*) Here, initrd is required by lvm to check thin-pools at boot time (I
use optional thin-provisonning-tools).
More info about that in an other post if needed.
