Linuxulator: running one's own small Linux in FreeBSD?

[Thomas Mueller]

Is it possible to run one's own little Linux in FreeBSD by null-mounting directory or partition on /compat/linux?

I am thinking in particular of my own cross-compiled version (from FreeBSD or NetBSD on amd64 aka x86_64) still in infancy, with busybox or otherwise?

This busybox is cross-compiled for Linux (i486-linux-musl or x86_64-linux-musl).

Currently, this is on UFS2 aka ffsv2 file system.

Would the Linux C library have to be glibc, or could it be uClibc-ng or (more likely) musl?

I would want to be able to try with more than one infant Linux installation (one at a time), hence the desire to null-mount on /compat/linux rather than copying to /compat/linux.
