Good understanding about kernel
Hi , I check the kernel file it's come to me too big . For example with default installation My kernel size is 5,473,370 You will say because of GENERIC kernel too many driver support for this reason it can be . My question is here 1) in document said that FreeBSD support dynamic module okey but after that same documentation said that because the functionality is so tied to kernel that can not be made dynamically loadable ? a) For What functionality ??! and Why it can't be ?!!! Because in Linux possible to have too small kernels ... I know that small kernels always work faster ... I think FreeBSD consider this ?! b) I can not believe FreeBSD moduler support because I check /usr/src/sys/modules and all those files compiled and moved to /boot/kernel directory with .ko extansion ( I think this extansion FreeBSD module extansion ) But in Linux We can choose (almost everything like LVS , File System , Network Settings any Dirvers , RAIDs , File System ) this will be moduler or this will bein the kernel ( static ) with this configuration we can have small kernel ... Could you say me How can I choose this feture or driver will be moduler or not becasu only to things can poosbile put the start of line #or not .. How FreeBSD understand that This will be moduler or not c) in Linux we can create a boot disk with this boot disk if any problem occur on the boot we can up the system with this disket .. in FreeBSD with this big kernel it's not poessible I think . I want to learn What FreeBSD users do if FreeBSD dont open the system for any boot file corrupt or something ... ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

My question is here What's (statically) included in the GENERIC kernel, is listed in /usr/src/sys/i386/conf/GENERIC. You can compile your own custom kernel, as explained in http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html Don't forget to statically include every module that is needed to locate and load the kernel though (e.g. ata drivers), because you won't be able to kldload the initial modules without booting first. c) in Linux we can create a boot disk with this boot disk if any problem occur on the boot we can up the system with this disket .. in FreeBSD with this big kernel it's not poessible I think . I want to learn What FreeBSD users do if FreeBSD dont open the system for any boot file corrupt or something ... I use the LIVE filesystem on the FreeBSD ISOs. In combination with /stand/sysinstall (or /usr/sbin/sysinstall), option rescue, you can always repair a broken installation. Most of the time, the boot loader will allow you to boot an old kernel (say /kernel.old) if your new kernel is broken. FreeBSD's bootloader is much more stable/reliable than LILO ;) -- Cordula's Web. http://www.cordula.ws/ ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
