The advantage is that the size of the VDISKs are then controlled by
the directory entry. You don't need to have special handling in the
PROFILE EXEC for each virtual machine if a different size is
required for whatever reason.

Hi Adam,
Thanks for the information. What advantage does defining the VDISK in
the directory and using SWAPGEN in the PROFILE with REUSE over not
defining them in the directory and just doing the SWAPGEN in the
profile
without REUSE? Just trying to make sure I understand this!
What Rich said: it can give you better control over who gets how much
swap space. Although, er, you DO need special handling in PROFILE
because the number of blocks can't default.
The usual case for it is: "I only want most users to be able to
request 50MB of VDISK, but I have one large Linux guest that needs
300MB." You can set syslim and userlim appropriately and just give
that one guest a giant VDISK in his directory.
