Since I have ZFS as my Proxmox file system, I wanted to use UFS for OPNsense. But no matter what I try I always get an error: "Partition destroy failed" during installation. I tried with BIOS and UEFI (where I had to disable secure boot). This is with OPNsense 26.1.2 on a fully patched Proxmox.
A test with OPNsense 25.7 which I still had around worked but I would like to have the most recent version, if possible.
Any ideas what is going wrong and how I can fix it?
Thanks

The 26.1 images are also available for that reason.
New images are still planned but it's not a priority at the moment.

another option with installing opnsense with zfs on top of proxmox with zfs, is do these 2 things:
opnsense uses 128k record size, proxmox defaults to 8k. make the opnsense zvol ahead of time (don't let the wizard do it)
zfs create -V 64G -b 128k rpool/data/vm-100-disk-0that minimizes the write amplification when the record size mismatches.
to eliminate the double arc, set the caching to metadata only.
zfs set primarycache=metadata rpool/data/vm-100-disk-0
for the level of IO opnsense does, this pretty much eliminates zfs on zfs issues, imo. enough so that trying to get UFS working seems like more effort than its worth...
