No. FreeBSD is released as a complete operating system and not just a kerne= l=20 with distributions arround it. If you want to run FreeBSD you will have to= =20 run the operating system. But of course you can get the code you want by cvs. > > I'm curious if I could do something like in was doing in Linux before > linux 2.6 was officially released where I had the choice to run a 2.6 > test kernel or load a 2.4 kernel so I could try out some of the new > features without dedicating my system to running it full time in case > of any stability problems.

You have the choice to run -RELEASE, -STABLE or -CURRENT. What you are looking for is -CURRENT. There you can test anything you want = and=20 take part in development. =46or production use you should run RELEASE and you can also run a second=20 installation on your test machine like -STABLE. =46or more info see the FreeBSD Hnadbook, especiallay: http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/current-stable.ht= ml > > Also, are there many patches for trying out new features like improving > latency on a system or trying out a new scheduler? (These are just > examples I took from linux.) Indeed, there is currently a new scheduler in FreeBSD. You can choose it by= =20 compiling your own customized kernel. Also see the handbook for further inf= o=20 (You need "options SCHED_ULE") > > And lastly, is there anyway to emulate running a linux device driver > or is it easy to port it to freebsd? No device driver. But you ave a userland emulation. =2DHarry --Boundary-02=_HifCAGQP5TxDOUc Content-Type: application/pgp-signature Content-Description: signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (FreeBSD) iD8DBQBACfiHBylq0S4AzzwRAscuAJ9b0vdX2NrIcGT+OBRZ38za4/HN8QCgjWA2 GFfelyB41NqdvFSMIIRJeds= =9Z+Z -----END PGP SIGNATURE----- --Boundary-02=_HifCAGQP5TxDOUc--
