yjftsjthsd-h, I'm curious so I looked it up but couldn't find anything. AFAIK POSIX only specifies operating system behavior and doesn't specify any actual apps but I could be wrong there. In any case, the rise of containerization has brought many nano Linux distributions that often have even fewer packages than even the most minimal distributions of years past.
