RAM file system

AEL systems make use of a RAM-based file system (tmpfs) mounted on /var/tmp. The

contents of this file system are not preserved through reboot. The RAM file system

grows and shrinks to accommodate only the size of the files it contains. This means

there is very little overhead.

To prevent the RAM file system using the whole of RAM, the file system is constrained

to use a maximum of 4MB of memory. You can change this by editing /etc/fstab and

changing the size= parameter for /var/tmp.
