mount: special device LABEL=/boot/efi does not exist

[gdha]

After a successful recovery of RHEL we got an error at start-up:

mount: special device LABEL=/boot/efi does not exist

in (saved) log file I noticed:

+++ echo -e 'Creating vfat-filesystem /boot/efi on /dev/sda1'
+++ mkfs.vfat /dev/sda1
+++ dosfslabel /dev/sda1 options=rw

In the disklayout.sh file the label was saved correctly, but the issue is that we're missing an uuid entry (or a fake one) so that the label was the options entry instead.
To fix this change:

# diff 23_filesystem_layout.sh /tmp/gratien/23_filesystem_layout.sh
51c51
<                 echo -n " uuid= label=$label"

---
>                 echo -n " label=$label"

will test this immediately :-)
