- Ultimately this seems to trace back to a bug in the Linux kernel. Sadly, I don't see any reason to believe it's going to be resolved in the kernel any time soon.
- A potential medium-term fix is for Bedrock to offer the corresponding functionality via a kernel module, and to fall back to a FUSE implementation if the module is unavailable (e.g. if you reboot into a kernel that breaks compatibility with the module). The proper way to do this would be via dkms, but is thus blocked on cross-distro dkms functionality. This is a realistic route, but given limited project resources it's likely quite a ways away.
- The long-term fix is to upstream Bedrock's required functionality into the Linux kernel directly. The main issue here is that we don't know exactly what functionality Bedrock actually needs here; it's often changed quite a bit from release to release. Keeping it out of the kernel tree - and using dkms/FUSE - offers needed flexibility in Bedrock Linux's pre-1.0 period.
