Doing that results in a / partition of 512MB, although the entire disk is 500GB. This is enough for installing the base system. However, building and installing a custom kernel (a smaller one than GENERIC, fwiw) already overfills the / partition, causing the kernel installation to exit with an error. I'd recommend to increase the default size of / to 1GB if the total size of the disk permits this. On my box, the current kernel, the old kernel, a good copy of the current kernel, and whatever sysinstall else puts into / take up approx. 775MB. >How-To-Repeat: Boot from an amd64 netinstall CD. Begin a standard installation. Use fdisk to allocate the entire HDD to FreeBSD. Enter disklabel and use the Auto Defaults option to automatically size the partitions. >Fix: It is easy to work around by manually sizing the partitions. Still, it might be a better idea to teach disklabel to use more appropriate defaults. >Release-Note: >Audit-Trail: >Unformatted:
