# mkdir /mount-point
where mount-point is the directory on which the TMPFS file system is mounted.
# mount -F tmpfs [-o size=number] swap mount-point
Specifies the size limit of the TMPFS file system in MB.
Specifies the directory on which the TMPFS file system is mounted.
To set up the system to automatically mount a TMPFS file system at boot time, see Example 2–3.
# mount -v
The following example shows how to create, mount, and limit the size of the TMPFS file system, /export/reports, to 50 MB.
# mkdir /export/reports # chmod 777 /export/reports # mount -F tmpfs -o size=50m swap /export/reports # mount -vExample 2-3 Mounting a TMPFS File System at Boot Time
You can set up the system to automatically mount a TMPFS file system at boot time by adding an /etc/vfstab entry. The following example shows an entry in the /etc/vfstab file that mounts /export/test as a TMPFS file system at boot time. Because the size=number option is not specified, the size of the TMPFS file system on /export/test is limited only by the available system resources.
swap - /export/test tmpfs - yes -
