I just switched from raspberry pi os arm64 which supports netbooting from nfs vers=4.2
With ubuntu (server 21.10) console spams: Begin: Retrying nfs mount ... 4.2: invalid value for vers
I tried rebuilding the kernel with: CONFIG_NFS_V4 y CONFIG_NFS_V4_1 y CONFIG_NFS_V4_2 y CONFIG_NFS_COMMON y CONFIG_ROOT_NFS y
But that alone does not fix the issue.
