feature flags should work with derivative zfs implementations.

<div>Hi,</div>
<div>A file system related generic question:</div>
<div><br>
</div>
<div>I am looking to keep one of my GPT Partitions on my
disk to be a file system that both Illumos (Solaris) /
FreeBSD and Linux can read. This will be primarily to
store data. I know there's vfat (fat32). Wanna know if
there's anything better (non-MSFTish) out there.</div>
<div><br>
</div>
<div>Other than exfat, fat32 what else do we have?</div>
<div><br>
</div>
<div>I started using openzfs (which is at version 2.3.3 rn)
on linux. However, there's probably a version difference
with Illumos/OI.</div>
<div>Since, I couldn't complete the OI setup on my machine
yet I don't know what version of zfs we are using on OI. I
am not quite sure if zfs will be a viable option due to
lack of compatible versions (openzfs on linux and ZFS on
illumos).</div>

<p>Hi!</p>
<p>Yes, if you use the "-d" option with zpool create, all of
illumos, Solaris 10+, BSD, Linux with installed ZFS support can
read/write to it.</p>
<p>You are able to enable additional features one by one, whilst
checking if the features are available to all of you favorite OS.</p>
<p>BTDT.</p>
<p>BTW, i've tried a ZFS Package for Windows 1-2 years ago, that
worked in my test case..<br>

<p>For my camera sd card i use EXFAT, there's a pkg on OI available
(built from <a href="https://github.com/relan/exfat.git" target="_blank">https://github.com/relan/exfat.git</a> - uses libFUSE)</p></div>
