Portable File System (PFS) Obsoleted
Portable File System (PFS) was intended to allow access to a variety of CD-ROM file
system formats. PFS was originally adopted by HP to provide accessibility to the
RockRidge Interchange file system format on CD-ROM file systems.
obsolete for June
2004
PFS is obsolete, and no longer supported on any HP-UX release. The PFS file system
interfaces will be discontinued (no longer delivered) on HP-UX 11i v3. PFS was
originally adopted by HP to provide accessibility to RockRidge Interchange file format.
The equivalent functionality is now provided by HP via the HP-UX CDFS file system
type and HP-UX's standard file systems commands.
With the HP-UX support of Rock Ridge extensions in CDFS, there is no longer the need
to execute the special PFS daemons or commands. The standard Unix file systems
commands and procedures can be used to access CD-ROM file systems (including
ISO-9660 file systems with Rock Ridge Extensions), just as any other file system. The
performance while accessing CD-ROM file systems using CDFS is significantly better
than the performance of PFS.
For HP-UX 11i v1, the enhanced CDFS and mount/umount commands are provided in
patch form: PHKL_28025, PHKL_26269 and PHCO_25841. The patches PHKL_28025
and PHKL_26269 are included in the HWEnable11i bundle, which is automatically
installed with the Operating Environments.

The patch PHCO_25841 is available on the
Quality Pack media.
With these HP-UX 11i v1 patches, a mount command option (mount -F cdfs -o rr)
must be used to enable support of Rock Ridge at mount time.
Documentation
See the mount (1M) and mount_cdfs (1M) manpages for the replacement functionality.
Enhanced AutoFS Available on Software Pack

enhanced to provide the features of the SUN ONC+ version 2.3 AutoFS product. This
enhanced version of AutoFS is known as Enhanced AutoFS. With the Enhanced AutoFS
