targetPlatform vs hostPlatform is still a little confusing to me. I believe this is the correct fix to remove pam from buildPackages (but not in host packages), but a second set of eyes would be nice

if you're trying to use targetPlatform:

are you trying to make a compiler that requires rebuilding to change what machine it generates code for?

• yes: okay, use it. arrgh.
• no: do not use targetPlatform

i am all for it if it can be fixed in the freebsd mkderivation, but i don't know enough freebsd/stdenv wizardry to fix it there. I knew how to fix it in util-linux, but i won't make a claim about that being the best fix

of course the lastlog isn't dependent on pamSupport rn, i meant even with the following patch it still goes to inf-rec:

okay i would like to clarify that i am saying that making util-linux depend on targetPlatform is not acceptable. that would make anyone cross compiling to rebuild everything in buildPackages that depends on util-linux

Everything in buildPackages has to be rebuild anyways since it can't be shared with native pkgs

they are shared
