problem with initramfs-tools

[Ralf Mardorf]

Hi,

the OP wrote that it was built for a Raspi course in their hackerspace.
As for the screenshots, the Raspberry Pi desktop appears to be a variant
of LXDE. I don't know how close Lubuntu's LXQt comes.

What applies to Debian also applies to Ubuntu flavors and probably most
major distributions, 32-bit support has been discontinued and even with
64-bit support one should not assume that 64-bit CPUs from antiquity
with the leanest and oldest instruction sets are still sufficient.

Regards,
Ralf
