Linux as a library is unlikely since GPL enforces a boundary between Linux and its users. Otherwise it'd've become just another statically-linkable asset copied

Linux as a library is unlikely since GPL enforces a boundary between Linux and its users. Otherwise it'd've become just another statically-linkable asset copied into a bunch of corporate codebases long ago. glibc uses the same strategy too w/ LGPL. Folks wanting to overcome the latencies and bloat these barriers create, should consider the problem might be more about politics than engineering.
