[-- Attachment #1 --] (I am not subscribed so please CC me) The ZFS layout uses the zroot/ROOT/<BE> to support boot environments. The problem with it is that /root is part of the BE. Home directories are properly outside of the BE. /root should really be outside to persist history and other changes to root's homedir through BE changes/upgrades. This is quite noticeable if you create a new BE (beadm create; beadm mount) and then installworld/kernel into it, then activate and reboot. All of your history and /root changes are missing for the period between creating the BE and rebooting. Something like this is needed: > --- usr.sbin/bsdinstall/scripts/zfsboot (revision 263620) > +++ usr.sbin/bsdinstall/scripts/zfsboot (working copy) > @@ -128,6 +128,8 @@ > > # Home directories separated so they are common to all BEs > /usr/home # NB: /home is a symlink to /usr/home > + /root mountpoint=/root > > # Ports tree > /usr/ports compression=lz4,setuid=off Though, I am unsure on whether we should make a zroot/root dataset and mount it in or mkdir /usr/home/root and symlink /root to it. The symlink does cause mergemaster confusion though. I have no opinion on where we create the root dataset, as long as it is outside of ROOT. -- Regards, Bryan Drewery [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJTLYSwAAoJEDXXcbtuRpfPSw4H/iAd5d1Gy4RtbvpgS1+W53fC Z82n4an0gbXXneOstI+3gngJEVC27ib4m8TUAh0fO8L6hl9pmiu3q0kZpXHLSaUL fgkonlg8QwVcAD8t7K0GVlq43HThJLafetf1cM6LYuwa1vX2JJkAQHeNc5HC+TcX 6zPDjP6q53Bx0lFudXfspHxK2ywa2G2GXfcwbGZheP9dMUCTAuse7ajkc6mHlpja al6361vVRAD9lwkQh4R4BrKbWrb3nCl0/IxlbUfh67x0qCJkR69kHfGSvfi9Y94U cPVFio56WwuxlQ/+Ixi128m7UaAz9yHquIFUI8NGfeeU2yPxVKkWh9Wzo/fz3i0= =DdYv -----END PGP SIGNATURE-----
