If this is true, can you then explain the following:  when you create
swap space on an HP disk drive, you may not change the size without
reformatting the disk.  I was told that this is because the swapping
space is in the old file system and therefore static.  If anyone knows
how to change the swap size dynamically ( we use SDRC CAD programs
that are real swap hogs ) please let me know...

(By the by, I am going to take the results of this to HP to update
their UNIX SysAdmin course.  Seems they are a little out of date...)
