alexis.marshlabs.gaertner.de is an OLinuXino
ARM-Board. It still runs the original Debian
wheezy distribution which, by now, is "a bit" long in
the tooth.
There's a reason for that old system. In earlier years, the special MALI-400 GPU support tied to the 3.4 linux kernel prevented an upgrade.
In the recent past, though, the mainlining efforts have made huge steps forward.
Today, I downloaded the Olimex-provided images for their "Armbianish" Debian-buster and Ubuntu-bionic releases, and even more current versions are afoot. Another candidate for the upgrade is Arch Linux ARM.
I need to find out if its possible to use a btrfs root filesystem. This would be just great for an extensive systemd-nspawn/machinectl setup.
I still have 90 GB unassigned on the 120 GB SSD and two unused partition entries in the MBR, set aside from the start for such an upgrade.
I don't dare to do the tests during the week: The board serves as XDCP, font server, and TFTP server for the X terminal in the kitchen, as well as for the telephone (tftp). It's also the DNS server for the marshlabs. So, I wouldn't mind a rainy weekend.
