Great
Super!
I've merged this to master now which means it will be in the latest beta in 15-30 minutes and released in v1.59
I may put the fix in 1.58.1 also. It is a little bigger than I'd usually like for a point release fix though...
You can set the global options as before, or you can set a local option with _config. Taking a squint at the code, I think the VFS initialisation doesn't use this so will only use the global flags.
