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
And being able to boot from NFSv4 has also made overlayroot work. I just
need to go back and ensure that it still doesn’t work with NFSv3, just
in case it was fixed by something else...

Whilst trying to understand the problem I looked at the source of
nfsmount in klibc. Nfsmount has a switch statement in which it checks
the value of nfsvers and only proceeds if it is 2 or 3. Given that my
version of nfsmount, compiled with klcc, can indeed mount using NFSv4 I
suspect that in libc'
Done it! I've managed to boot my RPi4 with Ubuntu Jammy off an NFSv4
share using the workaround from https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=409272#14 .
I created the file in the attachment and compiled it with klcc. If
anyone else wants to use it they'll have to edit the file, put thei
Good point: since this is the first bug I have ever actively pursued,
this is one of possibly many avenues I should follow.

I will test the work-around, but I won’t get round to it before the end
of the week.

Thanks Juerg, you’ve been very helpful.
Presumably there is no quick fix for this because of the klibc/glibc
thing, so it’s an architectural rather than a programming issue. And it
needs to be fixed in Debian rather than in Ubuntu.
I’d offer to help but I arrived here after drilling down from a

Thanks, I’ll look at that.
I note that this issue is now a confirmed bug. What does that mean in
practical terms? Will it be dealt with this week, this month, this
year…?
I need to be able to boot from NFSv4. If RaspiOS can do that it might
make sense for me to move after 15 years from Ubuntu to
The upstream bug is in Debian 11. The current version of RaspiOS, which
seems to support booting from NFSv4, is a Debian 11 derivative. That
means that RaspiOS has fixed it for Debian 11. Is it possible to copy
the RaspiOS solution?
