Hi there,

as per of the following article:
https://www.freebsd.org/doc/en/articles/linux-emulation/article.html under
the section number 5.2, the author of the article says that the Linux
kernel which they work to emulate it in FreeBSD is the 2.6 kernel version.
he also stated there that setting the "compat.linux.osrelease" via sysctl
to another values than 2.6 influence only on the version number which
is outputted by the uname command.

my question is if there is a plan to add support to emulation of the Linux
kernel of higher Linux kernels like 4.5.x with all of the features of those
kernel versions. it is to say, when one will set the "compat.linux.osrelease"
to version 4.5.1 for instance, it will not only affect the version that
is outputted by uname but rather will enable all the new features of the
4.5.x kernels if any.

Regards,

atar.

There's probably someone with plans to update the Linux emulation. But
that's a lot of work. Either someone has to do it in their spare time,
or someone has to pay them to do it.

So I really have no idea when either of those things may happen.
