Why is HP-UX the only OS that doesn read my RockRidge CDs correctly?
The answer is, because Linux and Sun workstations load RR extensions natively while with HP-UX you have to use PFS (Portable File System) which is, luckily, included with HPUX10.x. Here is what you need to do to read ’em: 0) Check that the directory containing the PFS utilities (usually /usr/sbin) is in your PATH.
