This suggested policy change is welcome. As per https://bugs.launchpad.net/ubuntu/+source/linux- raspi2/+bug/1852119/comments/2 the argument was that the RPI4 only has 4Gb of ram.
"we do not support ZFS unless you have at least 4GB of memory free. Today the 8Gb RPI4 was announced. https://www.raspberrypi.org/blog/8gb-raspberry-pi-4-on-sale-now-at-75/ I'm no expert, but I suspect that this device will be able to handle 4GB of memory free with ease... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1874519 Title: ZFS installation on Raspberry Pi is problematic Status in zfs-linux package in Ubuntu: New Bug description: Version: Ubuntu Server 20.04 - preinstalled 64-bit image for Raspberry Pi. ZFS on the Pi under 20.04 is currently a bit problematic. Upon issuing the command 'zpool status', I'm helpfully directed to install zfsutils-linux. When I do this, it complains that it cannot find the ZFS module, then errors out. Worse than that, the zfsutils-linux package does not depend on the zfs-dkms package, so it doesn't attempt to build the ZFS kernel modules automatically. The workaround is to install zfs-dkms, which builds the required kernel modules. (Once this has been done, the usual errors when installing the zfsutils-linux package, caused by there being no ZFS pools on the system, can be worked around by creating a zpool, then rerunning 'sudo apt install zfsutils-linux', as with previous versions of Ubuntu and Debian). I have not tested on other hardware platforms - this problem may also exist on other platforms where the user has not selected to install to ZFS. I have selected 'zfsutils' as the affected package, which is not the name of an actual current package, since launchpad won't let me submit the bug without selecting a package, however it's not clear to me that the problem is caused by that package.
