[Bug 1882980] [NEW] unix extensions disabled by default

[Max-Ulrich Farber]

Public bug reported:

when mounting a cifs share by the command line
sudo mount -t cifs //192.168.178.23/Bilder_klein /mnt -o guest,rw
the cifs unix extensions are disabled by default. The mount option `unix` or `posix` is refused. 

The command `mount` shows: 
`//192.168.178.23/Bilder_klein on /mnt type cifs (rw,relatime,vers=3.1.1,sec=none,cache=strict,uid=0,noforceuid,gid=0,noforcegid,addr=192.168.178.23,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,rsize=4194304,wsize=4194304,bsize=1048576,echo_interval=60,actimeo=1)`
Therefore the option `nounix` has been set by default, not according to `man mount.cifs`.
