Memory File System (MemFS) 2.0 for HP-UX 11i v3

recommends that you not use MemFS to mount /tmp and any file systems which
contain critical data that require consistency.
• A limitation with MemFS and Ignite-UX (and other products) is that there is no
support for /tmp or for /var/tmp as MemFS file systems. MemFS file systems
should be used only to hold application transient files. The file system and all its
contents will be lost with an unmount or reboot operation. Ignite-UX uses the
information stored in /tmp during the install process and therefore the /tmp file
systems cannot be MemFS based.
