[OpenAFS] creating system:ptviewers for existing cell...

[Rudolph T Maceyko]

OK, I've used AFS for quite some time now, but I'm stumped.  How would 
I create this pts id for an existing cell?

> ** A new system group is created  for new cells (system:ptsviewers
>    with id -203).  If this group exists, members of this group can
>    examine and read the entire protection database.  They can examine
>    all users and groups and can get the membership of any group.

$ pts creategroup -name system:ptsviewers -id -203
pts: Badly formed name (group prefix doesn't match owner?) ; unable to 
create group system:ptsviewers with id -203

$ pts creategroup -name system:ptsviewers -owner system -id -203
pts: User or group doesn't exist ; unable to create group 
system:ptsviewers with id -203 owned by 'system'

Do I really have to create a 'system' pts user in order to make this?

Thanks,
Rudy
