Hi,
You said no data is to be stored when powered down. What do you need
the overlay for then? Just mount to a tmpfs as '/' and centos as
'/usr', which is something that systemd supports out of the box. You
will need at least some files in /etc for this to work, and I just
have the initrd untar
To be clear, I am trying to introduce the minimal change possible to Centos
8 (due to outside constraints). Also past initial/lab development, the
embedded system goes on a trailer, and operates in (network) isolation for
months or years. Not so much a CI sort of setup. Did read the 0pointer
