To be honest, I for one would muuuuuch rather have a bsd kernel that takes a bit more time to boot, than a Linux one. Have you seen the rate at which debian publishes kernel updates ? We reboot some servers every week here, to apply this or that new kernel. Bsd takes longer, but over the course of a month we might reboot them once vs thrice for Linux. Overall, and discounting all the upgrading hassle, who boots faster now ? 1x freebsd or 3x Linux ? ;) To accelerate boot time you may also recompile a custom kernel and remove support for all the stuff you don't need, like all these outdated NIC drivers, wifi, scsi if you run sata... I run kernels with support for just one sata raid controller, 3 NIC drivers, remove support for all the USB stuff except the keyboard in case we need local console access, remove UFS ACL support (never used it, not sure I ever will). Hell I even remove support for the parallel port... Dramatically speeds up the boot process._______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
