NFS v kernelu je opět zaseknuté. Je to způsobeno pokusem o NFS mount z VPS, kde nejsou nainstalovány nebo neběží NFS služby, což se snadno stane na minimalistických distribucích typu Alpine.

NFS in the kernel is stuck again. We've identified the issue, it was caused by attempted NFS mounts while the userspace services were not installed/started, which is common on minimal distributions such as Alpine.
