Root in grub-efi-amd64 with raid1
In setting up raid1 I have to specify root in two lines in
dpkg-reconfigure grub-efi-amd64:
set root='.....'
linux /boot/vmlinuz-4.8.0-1-amd64 root=UUID=..... ro quiet
but I don't see how.
For the setup I follow the tutorial/blog of Francois Marier:
https://feeding.cloud.geek.nz/posts/...d-on-existing/
with adaptations for my situation, which is:
- debian stretch
- two disks, with partitions:
/def/sda1 /dev/sdb1 for efi, no raid
/def/sda2 /dev/sdb2 for raid1 on /md/data
/def/sda3 /dev/sdb3 for raid1 on /md/swap
I chose /md/data and /md/swap in stead of the usual md0, md1 etc,
but in the grub2-syntax I couldn't find how to specify root now.
In following Marier, all went well till I came to step 5:
Reboot using the RAIDed drive and test system:
my roots were wrong, and dpkg-reconfigure didn't show a window
in which I could specify my raid devices.
