Why to build Linux you always have to start with Linux, is there anyone who bootrapped it from freebsd or any other OS, minimalistic systems like https://niedzejkob.p4.team/bootstrap/ , etc?
Comparing to https://github.com/fosslinux/live-bootstrap your pseudo minimalistic arch pacstrap or Debian debootstrap are over fat of binary seeds and still you cannot get rid of Linux env in building the crusial packages.
