Every time you do a "make installkernel" (it's integrated into "make kernel"), the old kernel gets saved in /boot/kernel.old with all its modules. In addition to that, you can have an arbitrary number of different kernels in the root/boot file system. To switch between the kernels, escape to loader prompt on the boot menu, type "help" to see available commands (you'll probably use "unload", "load" and "boot", in this order). --------------enig6072C7723784809735151390 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFHzp3qldnAQVacBcgRAr/FAKDAzs4/14f/oayv33205ir73qY5eACcDkBo Y9tEZ4mRk4KdkKUQSXIpPD8= =tU57 -----END PGP SIGNATURE----- --------------enig6072C7723784809735151390--
