I want to put my /tmp partition in RAM and I got the following

from the fstab's man page:

The problem is that I don't want to have any swap in RAM, only my /
tmp
partition so I'm wondering if I simply remove the "swap" entry from
that line if that would work?
technically, swap is never on memory. swap is memory written
to the disk (when data is in memory it is either used or cache)
what you wrote is the correct way to create a partition in
memory (i do the same for my swap, the difference is my disk
is one 1 gb / and 95 Gb cgd disk but it is just for the fun
of doing it, i am not yet that paranoid...)
i suggest you to keep the swap entry. on bsd systems it wont be
used that much, and when it does you have usually trouble on your
hands (your mileage and size of flames coming from the server
might vary).
if you are worried and paranoid, you can create a partition,
mounted on each boot with a random key for your swap and tmp and
that key will be forgotten on each reboot and a new random one
used.
keep the swap entry. the /tmp one is good and that's how
you create one to put your /tmp in memory.

Ok so I added that entry and it worked fine except for one problem and
that is root only had permissions to write to that directory so some
services did not start up properly. I then gave the /tmp directory
0777 with chmod and rebooted my machine but it set it back to rwxr-xr-
x...
How do I have it so that anyone can write to the directory when the
computer starts up?
Thanks,
