Solved default layout, /usr not mounted.

Hi!

I have just installed the system and while looking and customizing the ZFS datasets I noticed
zroot/usr is not mounted, and so /usr/* are actually in zroot/ROOT/default.

Why? I mean, why the installer create that dataset by default but does not install the data in there?

Is /usr restricted to be used in a separated datase like /etc? I want to fix that in here. ;)

This is the complete layout:
Code: 
NAME                            USED  AVAIL  REFER  MOUNTPOINT
zdata                           223G   227G   496K  none
zdata/home                      222G   227G    96K  /home
zdata/home/alex                 222G   227G   188G  /home/alex

Is there a way to create a single snapshot including all datasets at once?

Many thanks! :)

The -r flag recurses but the snapshots will be individual for each recursed filesystem. You won't get a single snapshot with all the datasets included.

So a zfs snapshot -r zdata@mytest for example, will create the snapshots zdata@mytest, zdata/home@mytest and zdata/home/alex@mytest.
 
I was aware of the recursive but I would like to take a monthly single entire one. But, if not possible, ok. :rolleyes:

Thanks!

It's for boot environments. Short intro here that should answer your questions: https://blather.michaelwlucas.com/archives/2363

Note that you already crippled boot environments by creating zroot/usr/local yourself. The data in /usr/local should be part of zroot/ROOT/default as well to make effective use of them. Right now if you update packages and something breaks in /usr/local you cannot simply "go back" by booting into another boot environment.
