Description Edward Tomasz Napierala freebsd_committer freebsd_triage 2013-08-17 14:10:00 UTC 
setproctitle(3) doesn't work (does nothing) after entering Capsicum
capability mode.  I think this is because it depends on sysctl(2).
Still, would be nice to either provide a workaround, or at least document
this limitation.

Log:
  Make setproctitle(3) work in Capsicum capability mode.  This makes
  ctld(8) child processes to indicate initiator address and name in
  their titles, similar to what iscsid(8) child processes do.
