Change:
Mounting NFS volumes stopped working without configuration change other than updates. Steps to reproduce the behavior: updated system as of 2023-09-18 from stable to mount a nfs volume Get the error The volume to be mounted Please run and paste the result.
I am having the same issue, with very similar messages: I am running: It happened between ..., the only suspicious changes are kernel changes. In particular, both 6.5.2-6.5.3 and 6.1.52-6.1.53 include the patch "vfs, security: Fix automount superblock LSM init problem, preventing NFS sb sharing" which I think seems suspicious, but I don't know enough to dig any further. Any help would be appreciated.
Gentoo . In that bug, someone bisected the kernel and identified the patch that mentioned as the culprit. This link to a kernel patch that fixes the issue was also posted and verified to work:
I hit this as well, hoping it gets fixed promptly. For now I've worked around it by using an older stable kernel on affected clients:
I am guessing it will be fixed in upstream soonish, will it be fixed in NixOS like the gentoo folks did? For now, I have confirmed the above patch works on my configuration: nevivurn/nixos-config
The patch worked for me, didn't know it was that easy to apply one

This patch works great! This issue still appears in , but the patch still seems to works if applied to that version.
