De handleiding zegt toch duidelijk iets anders:
* To use fstab, create an entry /etc/fstab that looks something like:
none /path/of/mount/point gmailfs noauto,username=gmailuser@gmail.com,password=gmailpass,fsname=zOlRRa
The username and password fields speak for themselves. The fsname is
the name of this Gmail filesystem. It is important to choose a
hard-to-guess name here - because if others can guess the fsname, they
can corrupt your Gmail filesystem by injecting spurious messages into
your Inbox.
* To mount from the command line, do:
mount -t gmailfs none /path/of/mount/point -o username=gmailuser@gmail.com,password=gmailpass,fsname=zOlRRa
or
mount.gmailfs none /mnt -o username=gmailuser@gmail.com,password=gmailpass,fsname=zOlRRa
