--- Begin Message ---Hi Thomas, Thanks for responding!

Have you already tried the FAIme service at > https://fai-project.org/FAIme/ Yes, I got an image from there (nice feature to let me include an ssh key, btw) and picked the "reboot computer after installation" option. I tried that iso as the CD on a local vm as a sort of "getting started" step, but it seemed to go into an infinite loop of installing. I tried ejecting the CD, but it didn't end with a system I could boot, so I'm not sure what I was doing wrong. But I figured I'd go ahead and try to see if I could launch that from local hard drive instead of as a CD. > Have a look at the dracut.cmdline manual > https://manpages.debian.org/testing/dracut-core/dracut.cmdline.7.en.html Thanks for that reference, very helpful. After a few tries, this menuentry gets me to where in my vm it looks like it's trying to do something with the .iso I've put into the hard drive: menuentry "jake fai" --class gnu-linux --id jake-fai4 { loopback loop (hd1,gpt2)/faime-PR5UDQU6.iso search --set=root --file /FAI-CD ifname=nat0:08:00:27:b0:02:bf ifname=hst1:08:00:27:b0:02:bf linux /boot/vmlinuz FAI_FLAGS="menu,verbose,createvt" FAI_ACTION=install FAI_CONFIG_SRC=file:///var/lib/fai/config rd.live.image rd.debug root=live:CDLABEL=FAI_CD ip=10.0.2.15::10.0.2.2:255.255.255.0::nat0:off:8.8.8.8:8.8.4.4 ip=192.168.56.90:::255.255.255.0::hst1:off quiet initrd /boot/initrd.img } But then it fails with: dracut Warning: /dev/disk/by-label/FAI_CD does not exist dracut Warning: /dev/root does not exist That comes after a minute or 2 of polling with this looking like the problem check: //lib/dracut/hooks/initqueue/finished/devexists-x2fdevx2fdiskx2fFAI_CD.sh@1(source): '[' -e /dev/disk/by-label/FAI_CD '] As a guess after looking through options, I tried adding this: rd.live.overlay=/dev/sdb2:faime-PR5UDQU6.iso But no joy. I tried a few variations, but I feel like it's stabbing in the dark a bit. This seems really close to what I'm aiming for, but I don't quite follow how to express what I have. Once I'm in the dracut shell after hitting that error, I can do: mkdir mnt mkdir mnt/disk mkdir mnt/iso mount -t ext4 /dev/sdb2 /mnt/disk mount /mnt/disk/faime-PR5UDQU5.io /mnt/iso And then I have /mnt/iso/FAI-XD and /mnt/iso/LiveOS/squashfs.img and such. So I feel like this is on the right track if I could find out the way to pass in the right context. Thanks for your help on this, and if you have a pointer to the right way to express this root location, I'd be very grateful. Best regards, Jake PS: I could perhaps use the root=live:https://example.org/something.img. is that supposed to be the squashfs.img inside the iso's LiveOS/, or is it supposed to be the ext3.img inside the squashfs.img's LiveOS/? But it seems a bit silly when the live iso is already on the local disk... PPS: In case it's helpful, I put the .iso into /dev/sdb2 with these commands (with the partition table pulled from sfdisk -d on /dev/sda and then tweaked by removing uuids.) cat > sfdisk_sdb_new.in <<EOF label: gpt device: /dev/sdb unit: sectors first-lba: 34 last-lba: 20971486 /dev/sdb1 : start= 2048, size= 2048, type=21686148-6449-6E6F-744E-656564454649 /dev/sdb2 : start= 4096, size= 2097152, type=0FC63DAF-8483-4772-8E79-3D69D8477DE4 /dev/sdb3 : start= 2101248, size= 18868224, type=0FC63DAF-8483-4772-8E79-3D69D8477DE4 EOF sudo sfdisk /dev/sdb < sfdisk_sdb_new.in sudo mke2fs -t ext4 /dev/sdb2 sudo mount -t ext4 /dev/sdb2 /mnt sudo cp faime-PR5UDQU6.iso /mnt sudo umount /mnt (Then it's just append my menuentry text to /etc/grub.d/40_custom, GRUB_DEFAULT=jake-fai4 in /etc/default/grub, and update-grub.)
