I'm on a managed machine but I'd like to create a folder stored in RAM for temporary storage, how might I do this?
AFAIK, you can't create a new tmpfs mount without root privileges.
However, many Linux distos provide a tmpfs mount on
/dev/shm that's writable by all users. If it's there, you should be able to
abuse use that to store your temporary directory.
[me@home]$ mount | grep tmpfs none on /dev/shm type tmpfs (rw)
On Ubuntu 11.10, it is mounted on
[me@ubuntu_home]$ mount | grep shm none on /run/shm type tmpfs (rw,nosuid,nodev)
Without the help of a sysadmin you can't. In fact you need him to use sudo to make you able to mount tmpfs or to put an ad-hoc entry in /etc/fstab .
The point is that mount requires special rights.
Ask your sysadmin
PS: if your system works with tmpfs mounted on /tmp, then you can create a folder there.
