The sysadmin is likely to need access to: 1) look at SysV IPC usage across the entire system 2) clean up after a process has died unexpectedly. Whilst it's possible for the sysadmin to enter the relevant jail and look at what is used in that jail, it's very difficult to get an overall view of the system in this way - especially if there are lots of jails. Robert Watson was also looking into this recently. -- Peter Jeremy
