Error Mounting SMB Shares on Big Sur

[ChrOst]

Hi,

as @greatkemo mentioned in JSSImporter#187 you cannot mount shares on macOS Big Sur (with Apple Silicon, haven't tried intel yet).

Is there a known fix? If not I'd write a patch which creates a tempdir (mktemp) and mount the share to that place. This should avoid the error when trying to mount/create a dir in /Volumes.

Cheers,

Additionally the output I see on an BigSur machine (censored some stuff):

JSSImporter: Checking if DP already mounted...
