Linux Emulation in FreeBSD
docs.freebsd.orgKeep in mind that this is not EMULATION.
The Linux syscalls are just implemented into FreeBSD.
In 1998-1999 they literally used FreeBSD with Linux Abstraction Layer and run Linux apps on FreeBSD instead of using Linux natively because it was faster that way.
Relevant 'press release' here:
Now! The real exercise would be to run wine for linux in that one (and of course, having FreeBSD running in a Hyper-V VM under Windows :D).
