podman without HOME

[abitrolly]

Is it possible to execute podman without HOME?

Looks like HOME is a hard requirement even for --version flag.

#!/usr/bin/env testscript

exec podman --version

Running podman with testscript fails.

#!/usr/bin/env testscript (0.028s)
> exec podman --version

I don't think it is possible, podman needs to parse config files before it sets up the cli commands/flags so there is no way around that even for something like the --version flag.

No config files == use defaults, no?

[Luap99]

yes but there is more initial setup magic happen, i.e. out code tries to set certain env very early on.

Do we need $HOME for podman --version, theoretically not. But the way the code is structures the core init logic runs always and it is very difficult to change that for just one command.

Can it fail-on-use instead instead of fail-on-everything?
