Hello, no, there were no errors before. The small box is updated on a frequent basis, so I'm sure there were no errors like those before or any other kind regarding I/O. I recall having read the commit description about the UFS2 enhancement. The NanoBSD image is created using UFS2/GPT partitioning scheme, if this is important to know. Regards, Oliver -- O.
