[OpenIndiana-discuss] Layout of zfs fs

[Harry Putnam]

I thought I would know the answer to this question eventually from
just using zfs.  I have not gotten any closer, so, seeking advice from
experienced zfs users.

What is the better way to arrange zfs fs:

I have data and ongoing work in three directories.  Directories that
most often appear like so

/usr/local/src
OK, I want to end up with zfs fs on `local', `src' and in my case
`git'

In my case, running ubuntu 20:10 /usr is also zfs and part of rpool.

I don't want these new zfs fs to go on rpool so have create a zpool
name of `p0'

So should I create the zfs fs  by
zfs create ... -o mountpoint=/usr/local p0/local
zfs create ... p0/local/src
zfs create ... p0/local/src/git

(the -p option may be useful above.. I just want it
to be clear what is being done)
 
ending with /usr/local/src/git

OR like this:

zfs create ... -o mountpoint=/usr/local p0/local
zfs create ... -o mountpoint=/usr/local/src  p0/src
zfs create ... -o mountpoint=/usr/local/src/git  p0/git

Again ending with  /usr/local/src/git

Is one way easier to manage or maintain?

any other pointers quite welcome
