--FfX2iGK5t5ehHnsE Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable My system was installed from 10.1 or 10.2 with root on ZFS and geli, but now it tracks current. It is not an EFI system. I'm trying to get boot environments to work, but the /boot symlink is throwing me off. I have two pools from the installer's layout; a small bootpool and zroot. The bootpool mounts at /bootpool and /boot is a symlink to it. > randy@mako /> zfs get mountpoint bootpool > NAME PROPERTY VALUE SOURCE > bootpool mountpoint /bootpool local >=20 > randy@mako /> ls -al /boot > lrwxr-xr-x 1 root wheel 13 Aug 12 2015 /boot -> bootpool/boot When I try to activate a boot environment, I get this error: > root@mako:/ # beadm activate r300358 > cp: /tmp/BE-r300358.FS6Xo6ot/boot/zfs/zpool.cache: No such file or direct= ory Because the new boot environment has a symlink to an empty directory: > randy@mako /> ls -al /tmp/BE-r300358.FS6Xo6ot/boot > lrwxr-xr-x 1 root wheel 13 Aug 12 2015 /tmp/BE-r300358.FS6Xo6ot/boot = -> bootpool/boot >=20 > randy@mako /> ls -al /tmp/BE-r300358.FS6Xo6ot/bootpool > total 9 > drwxr-xr-x 2 root wheel 2 Aug 18 2015 . > drwxr-xr-x 21 root wheel 29 May 21 16:23 .. Mergemaster complains about the /boot symlink as well. I'm not sure what the cachefile does or why it's there. It has a recent modification time, but neither pool seems to reference it. > randy@mako /> zpool get cachefile zroot > NAME PROPERTY VALUE SOURCE > zroot cachefile - default > randy@mako /> zpool get cachefile bootpool > NAME PROPERTY VALUE SOURCE > bootpool cachefile - default > randy@mako /> ls -al /boot/zfs/zpool.cache > -rw-r--r-- 1 root wheel 2512 May 21 16:23 /boot/zfs/zpool.cache What's the proper way to handle the /boot symlink with beadm?
