What are the options "Nosuid" "mode" "size" in /etc/fstab? tuxfiles.org does not help


When I read the doc on page

http://www.tuxfiles.org/linuxhelp/fstab.html

about /etc/fstab file then I miss there explanations for the options

"nosuid"
"mode"
"size"

What do they mean in detail?

Is "size" e.g. the inital start or maximum size of the (tmpfs) file system partition?

The options you mention are mount options.

Have a look here: mount

Example of the size option (tmpfs specific):
Quote:
Mount options for tmpfs
size=nbytes
Override default maximum size of the filesystem. The size is
given in bytes, and rounded up to entire pages. The default is
half of the memory. The size parameter also accepts a suffix %
to limit this tmpfs instance to that percentage of your physical
RAM: the default, when neither size nor nr_blocks is specified,
is size=50
