Why is a second "tmpfs" parameter necessary when mounting a tmpfs?

It's not an option – it's the device name.
Remember that the syntax for mount(8)
is:
mount [-t fstype] [-o options] device mountpoint
So even for filesystems that don't correspond to a specific device, you still need to give a dummy name, whether it's none
or tmpfs
or fluttershyfs
.

Excerpted from the documentation
So 'mount -t tmpfs -o size=10G,nr_inodes=10k,mode=700 tmpfs /mytmpfs' will give you tmpfs instance on /mytmpfs which can allocate 10GB RAM/SWAP in 10240 inodes and it is only accessible by root.
Please note the command line:
mount -t tmpfs -o size=10G,nr_inodes=10k,mode=700 tmpfs /mytmpfs
What makes me confused is the second
tmpfs
. The manual page says nothing on the optiontmpfs
, what does it mean? -
