What prevents "guix package --profile" profiles from being gc'ed?

[Christopher Allan Webber]

Heya all,

I'm a bit confused about profile management for profiles that *aren't*
your system or default user profile.

  guix package --profile=/home/cwebber/guix-profiles/test -i hello

then I run "guix gc", it seems like that profile is still kept around.

David seemed to think that maybe the profile link would be under
/var/guix/profiles/

It doesn't look like it.

What's keeping that profile around?  Will it ever get gc'ed?  Is it
somehow recorded in Guix's state files?

Just curious,
