Best-effort synchronization: Permissions issue

[stdedos]

Hello there,

I'd like to propose a consideration for the syncing algorithm. Feel free to ignore me if that feels too much.

When synchronizing (via terminal), I encountered the following issue:

Failed [<top-level-dir>]: Failed to set permissions of file /root-b/.unison.top-level-dir.6b5b6fbc8e15ffae793d6a68adebe9c0.unison.tmp to rwxrwxrwx: the permissions was set to rwxr-xr-x instead. The filesystem probably does not support all permission bits. If this is a FAT filesystem, you should set the "fat" option to true. Otherwise, you should probably set the "perms" option to 0o1755 (or to 0 if you don't need to synchronize permissions).                                                                                                                                                                                    

In my case, the root-a is fuseblk (ntfs), and the root-b is exfat.

(I would've considered the fat option to true, but is exfat a fat filesystem?)

exfat is fat, and fat really means 'deficient like fat'.
