Hi,
Another option is this.
The installer /usr/sbin/bsdinstall uses a script called /usr/libexec/bsdinstall/zfsboot. Zfsboot defines this:
#
# Default options to use when creating zroot pool
#
: ${ZFSBOOT_POOL_CREATE_OPTIONS:=-O compress=lz4 -O atime=off}
You can set this environment variabele to your liking before starting bsdinstall.
ZFSBOOT_POOL_CREATE_OPTIONS="-O compress=lz4 -O atime=off -o feature@block_cloning=disabled" bsdinstall
If you are booting from an USB stick installer you can also change the zfsboot script on the USB stick and restart the installer.
NB: don't confuse the option with ZFSBOOT_BOOT_POOL_CREATE_OPTIONS.
Regards,
Ronald.

<blockquote>Hi,<br>

When you create a new pool you can use something like this:<br>

<br>
I tried setting this on an existing pool. That gave me an error.<br>
# zpool set feature@block_cloning=disabled zdata4<br>
cannot set property for 'zdata4': property 'feature@block_cloning' can only be set to 'disabled' at creation time<br>
<br>
So to install a new 14.2 system you need to do some manual work to create the root pool with the options you prefer.<br>

I think that it would be nice if the installer has the option to set a feature like this to off. Is it easy to break out of the installer, create the pool before hand and use that pool?<br>

Hi Johan,<br>
<br>
The installer gives me the option to partition manually (which does not give me the option you are looking for) or open a shell which gives you all the power you need.<br>
<pre style=";white-space: pre-wrap;white-space: pre-wrap;">Partitioning
How would you like to partition your disk?
Auto (ZFS) Guided Root-on-ZFS
Auto (UFS) Guided UFS Disk Setup
Manual Manual Disk Setup (experts)
Shell Open a shell and partition by hand
[ OK ] [Cancel]
</pre>
<br>
I can't say if you will find it easy or not.<br>
Good luck!<br>
<br>
Regards,<br>
Ronald.<br>
