Can you show the lsdef of the node and lsdef of osimage ?

I found that if I add to the template
(/opt/xcat/share/xcat/install/ubuntu/compute.tmpl) this line, the boot
loader is installed automatically.
d-i grub-installer/bootdev string /dev/sda
I realize that that line is installing the MBR explicitly into /dev.sda,
and if whatever reason /dev/sda isn't present, it won't work. So I'm sill
wondering why the target location of MBR isn't calculated automatically.
For he records, this is the output of lsblk:

Yes, that was that! I reduced the debug to 1 and the ssh prompt is
no
more. Thanks a lot for the tip!
Next question: the installation now stops asking me where to install
the
bootloader.
This prevents the installation from completing in unattended fashion.
Where is that controlled in xcat?
┌──────────┤ [!!] Install the GRUB boot loader on a hard disk
├───────────┐
│
│
│ You need to make the newly installed system bootable, by
installing
│
│ the GRUB boot loader on a bootable device. The usual way to do
this
│
│ is to install GRUB on the master boot record of your first hard
│
│ drive. If you prefer, you can install GRUB elsewhere on the drive,
or
│
│ to another drive, or even to a floppy.
│
│
│
│ The device should be specified as a device in /dev. Below are some
│
│ examples:
│
│ - "/dev/sda" will install GRUB to the master boot record of your
│
│ first
│
│ hard drive;
│
│ - "/dev/sda2" will use the second partition of your first hard

Hello collective wisdom,
Does anyone know how to disable the SSH prompt during diskfull
installation
of Ubuntu 18.04.5?
