While installing a FreeBSD 10.1-RELEASE system I want to use UFS and encrypt the entire disk. I select "Open a shell and partition by hand" and follow these steps: ==================== # gpart destroy -F ada0 # gpart create -s gpt ada0 # gpart add -t freebsd-boot -s 512k -a 4k ada0 # gpart add -t freebsd-ufs -l boot -s 1g -a 1m ada0 # gpart add -t freebsd-ufs -l encrypted -a 1m ada0 # gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 ada0 # geli init -b -l 256 -s 4096 ada0p3 # geli attach ada0p3 # newfs -U /dev/ada0p2 # newfs -U /dev/ada0p3.eli # mount /dev/ada0p3.eli /mnt # mkdir /mnt/unencrypted # mount /dev/ada0p2 /mnt/unencrypted # mkdir /mnt/unencrypted/boot # ln -s unencrypted/boot /mnt/boot # vi /tmp/bsdinstall_etc/fstab /dev/ada0p2 /unencrypted ufs rw,noatime 1 1 /dev/ada0p3.eli / ufs rw,noatime 2 2 # vi /tmp/bsdinstall_boot/loader.conf geom_eli_load="YES" vfs.root.mountfrom="ufs:ada0p3.eli" # exit ==================== This work as expected, but I would like to avoid /boot being a symlink to /unencrypted/boot so I have tried this: ==================== # gpart destroy -F ada0 # gpart create -s gpt ada0 # gpart add -t freebsd-boot -s 512k -a 4k ada0 # gpart add -t freebsd-ufs -l boot -s 1g -a 1m ada0 # gpart add -t freebsd-ufs -l encrypted -a 1m ada0 # gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 ada0 # geli init -b -l 256 -s 4096 ada0p3 # geli attach ada0p3 # newfs -U /dev/ada0p2 # newfs -U /dev/ada0p3.eli # mount /dev/ada0p3.eli /mnt # mkdir /mnt/boot # mount /dev/ada0p2 /mnt/boot # mkdir /mnt/boot/boot # vi /tmp/bsdinstall_etc/fstab /dev/ada0p2 /boot ufs rw,noatime 1 1 /dev/ada0p3.eli / ufs rw,noatime 2 2 # vi /tmp/bsdinstall_boot/loader.conf geom_eli_load="YES" vfs.root.mountfrom="ufs:ada0p3.eli" # exit ==================== This result in the following error when booting the system: config: not a directory. loader: not a directory. gptboot: No /boot/loader on 0:ad(0p2) kernel: not a directory. gptboot: No /boot/kernel/kernel on 0:ad(0p2) FreeBSD/x86 boot Default: 0:ad(0p2)/boot/kernel/kernel boot: Does anyone have a suggestion on why the second method won't work?
