This or something similar will be the next step if I cannot get the packaged version to work. It is not the first time I am left wondering why something reaches the Debian archive if it does not work. I already noticed that the ARM installer advertised support for the RockPi nanocomputers but did not manage to boot at all.

There is another property of Nix I need: Nix never replaces a file, it only creates new files under different directories. This is important for me as I intend to use the same snapshot of the /nix volume connected read-only on multiple virtual machines. That way, I can install a new version of, say, PostgreSQL for one VM but the other VMs running the older version will not be affected at all until I upgrade them too. Do you know if pkgsrc can give the same guarantee? (I have also put the Debian /usr on a separate volume with a read-only snapshot shared between VMs. The fact that on Debian stable an upgrade does not require change in configuration files means I can upgrade the system, make a new snapshot and reboot the VMs on it and it will work. I even “mv /boot /usr && ln -s usr/boot /boot”. It seems to work. At some point I will write a blog article about it.) Regards, -- Nicolas George
