Multiple 'profiles' / replacement for 'KICAD_CONFIG_DIR'?

I’m trying to setup KiCad for use with two conflicting setups (different default templates, settings, plugins active, etc). I’ve tried to use the KICAD_CONFIG_DIR environment variable, but it’s completely ignored. Maybe I used the wrong keywords, but I didn’t find any replacement feature.

Is there any other way to use multiple profiles (on Linux)?

Try KICAD_CONFIG_HOME.

I did this.

$ KICAD_CONFIG_HOME=/ kicad

and it behaved as if running for the first time. Of course / is not a writable location for a subdirectory named for the version; I was just testing.

That worked! Thanks!
