  that is the help screen... I meant the full documentation on the 
website about the xrootd protocol.

  Yes. This means that whatever you write is matched by the exported 
namespace. Literally it should mean something like:

"this pathname can be put in a single partition with X bytes free"

  It can be useful to detect when your disks are full, but not to 
publish  a good estimation of the total free space into whatever 
external system.

  To get hints about how to deal with that in Alice, you have to ask 
Latchezar. AFAIK there is only the need of declaring it statically 
somewhere.
