[Koen Roggemans]

Thank you for this clarification, Julian.

For your info: here is fstab of one of my problem devices:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/nvme0n1p2 during installation
UUID=f02fe823-8605-48f6-823f-c20a5133ae8d /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/nvme0n1p1 during installation
UUID=4480-184B  /boot/efi       vfat    umask=0077      0       1
/swapfile                                 none            swap    sw              0       0


mount and grep for "boot" gives me 
root at 8RZ1PL3:~# mount | grep "boot"
/dev/nvme0n1p1 on /boot/efi type vfat (rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)

So /efi/boot is there and mounted

Background info: the devices were installed with a "minimal"
installation, created an OEM, captured and distributed using fog. They
only contain one disk. I don't change any disk / boot settings I'm aware
of.

I would be very happy to check any other possible problems to find the
root of this problem and avoid it happening in the future.
