  Interesting; I haven't seen the build fail in this way before, and as
Jeremy pointed out Incus builds properly in other places on official
infrastructure.

  For background on this particular part of the build, when I was
working on LXD packaging the TZ and HOME environment variables were set
to help make the build reproducible[0]. Later with Incus, I must have
noticed something in another of the manpages that was including the
build-environment HOME, so I set the override on all the generation
commands[1].

  When the `incus` binary starts it does try to create a configuration
file under ~/.config/incus/; based on the error it seems that the
homedir is "/build/", and that it's read-only?
