Sorry to come back to this, but I'm now trying to netboot Ubuntu 22.04.2, having found the above mentioned work-around for 20.04. Something has changed: I can no longer netboot from NFSv4 by replacing /usr/lib/klibc/bin/nfsmount with an NFSv4-friendly hack.
I am now getting the same error messages that nfsmount used to generate, but I have discovered that /usr/lib/klibc/bin/kinit also generates them. So I am guessing that in 22.04 kinit has taken over part of the work the nfsmount performed in 20.04. Any thoughts? I'll try to take a look at kinit tomorrow and see if I can find another work-around. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to klibc in Ubuntu. https://bugs.launchpad.net/bugs/1954716 Title: rpi nfsroot vers=4 not supported anymore? Status in klibc package in Ubuntu: Confirmed Status in linux-raspi package in Ubuntu: Invalid Bug description: I'm running `5.13.0-1011-raspi #13-Ubuntu SMP PREEMPT Fri Nov 19 18:40:23 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux` and have successfully set up netbooting on my RPi 4B (4GB). When I do not specify a `vers=` in cmdline.txt, NFS version 3 is used. I'd like to move to version 4, but unlike the setup described in https://forums.raspberrypi.com/viewtopic.php?p=1751741#p1751741, I cannot get `vers=4` (or any sub-version to work): the console logs `invalid value for vers.` for whatever I try.
