potentially supporting more OSs than Conda?

[dimpase]

It's not 100% clear whether Mamba ecosystem (i.e. Micromamba, Quetz, etc) is ready to support OSs beyond what's offered by Conda, e.g. FreeBSD would be a natural candidate.

(This is more of a question than an issue).

Hi @dimpase I don't think that there would be an issue in getting micromamba to run on FreeBSD. I guess that all dependencies and a C++ compiler are available!

However, one would also need to have packages for FreeBSD to make this worthwhile :) Most conda packages currently need a host-installed glibc -- I don't know how FreeBSD works -- does it have glibc?

By the way, you can already use "arbitrary" subdirectories by passing -c "mychannel[freebsd-64, noarch]" on the command line, for example (just need to have the corresponding files on the server)!

If we figure out a good way to name the subdir, we could also add it to the pre-configured ones (incl. automatic detection of FreeBSD) cf:

mamba/include/mamba/core/context.hpp

Lines 23 to 28 in 3553249

	#if defined(__linux__)
	#if __x86_64__
	static const char MAMBA_PLATFORM[] = "linux-64";
	#elif defined(i386)
	static const char MAMBA_PLATFORM[] = "linux-32";
	// armv6l and armv7l

Anything specifc you have in mind for the support?!

PS: there was a user who compiled micromamba on Alpine Linux which uses musl-libc and not glibc and I think that works perfectly fine (the problem is just with the available packages from conda-forge).

[dimpase]

it would be nice to have SageMath installable on FreeBSD this way.

host-installed glibc -- I don't know how FreeBSD works -- does it have glibc

no, it does not, normally speaking, its libc is a BSD-derived one, closer to the one in macOS, I guess.

However there is also a Linux compatibility layer, which uses a special FreeBSD kernel module, and Linux ELF binaries might require special branding - I never used it though, perhaps it can just take Linux mamba packages.

There is also libc6-shim, an adapter allowing for (limited) glibc compatibility.

There is nothing actionable here, so I am closing this issue for now. If you are interested in bootstrapping micromamba on FreeBSD or adding packages for FreeBSD to conda-forge or another channel, feel free to open with concrete issues :)
