IIRC the kernel goes > through a second round of querying dhcp for info. Thanks for your hints! I've read the diskless booting howto before, but I did not yet built a custom kernel. Now I have a custom kernel with: options BOOTP # Use BOOTP to obtain IP address/hostname options BOOTP_NFSROOT # NFS mount root file system using BOOTP info hints "GENERIC.hints" When I boot this kernel from disk, it shows the device hints, sends out dhcp-requests and tries to mount / with nfs. But when I load it over the net, i get the following: grub> root (nd) Filesytem type is tftp, using hole disk. grub> kernel --type=freebsd /freebsd-boot/kernel/kernel [FreeBSD-elf, <0x400000:0x446f54:0x0>,<0x847f60:0x7d600:0x4fce0>, shtab=0> 16438, entry=0x43f2b0] grub> boot The prompt disappears and the system reboots after approx. 25 sec. (The custom kernel has the same behaviour as the default kernel from the FreeBSD installationdisk) Where does it tell me where it thinks the root filesystem is?
