I have one box with only 200MB for /. I had already displaced out GENERIC with highly stripped down kernel which made for space. I did at one point run out of space and the stuff mentioned further down saved the day for me. >> new kernel, I need to move the kernel.old to a different slice to >> install the new one.

I do the make buildkernel KERNCONF=xxxxxxx. Realize you should not be running out of space on / during this procedure as the build is occurring in /usr/obj. You will only run out of space on / if the make installkernel KERNCONF=xxxxxx won't fit. > When I make the GENERIC kernel, I again run out of space (I still have > about 60MB free in /).

I don't remember for sure if this truly matters, or not, but I seem to recall the size of my kernel directories decreased dramatically when I placed STRIP= -s in /etc/make.conf. It seemed a favorable thing to do once upon a time and it's been there ever since. I thought the system variables had migrated to src.conf and the make.conf only applied to ports. In addition I also have in make.conf NO_PROFILE= true and in src.conf is WITHOUT_PROFILE= true. My stripped down kernels are 3.1MB for a 1 NIC driver and 3.4MB for a 2 NIC kernel. Of course, you won't get these small sizes for GENERIC! -Mike _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
