or pip-installed?

FWIW we're currently using this in custom grain to determine whether Salt is Tiamat-bundled

def _is_tiamat():
    return getattr(sys, "frozen", False)

although that's not really the case, in practice it's enough for us

adding @Ch3LL as we talked about this in the past on slack

[OrangeDog]

It would be very useful if it was in the --versions-report too.

@Ch3LL would you consider this for 3005.1? After 3006 it will be less useful if onedir becomes the only supported system.

I'm curious, what use-cases you have in mind for this grain? I.e. what would be done differently in your states or modules based on this grain?

An obvious one is the pythonexecutable grain that no longer points to a Python interpreter and needs to be used differently based on the package format. But it can be handled differently based on its value only

[OrangeDog]

If salt is installed with classic packaging, then people probably want to use pkg.installed for additional dependencies. But if it's onedir then they need to use pip.installed instead.

[Ch3LL]

Since this is a feature request, it would need to go into 3006 not a point release. There is still value in 3006 since there is still different ways to install Salt: pip install and installing from packages that OS's provide

[Ch3LL]

I've added #64446 , but I have not been able to determine a way to programattically determine if Salt was installed and running from pip. I'm open to suggestions in the meantime while I continue to investigate.
