I have a machine running woody and another running sargs. When the big switchover comes, I want the woody machine to continue running woody and not follow stable to a big change to sarge. Oh -- I will eventually change to sarge, but at a time of my choosing, and with suitable parallel operation: this machine is in use 18/6, if not 24/7. How do I set it up to make sure I stay with woody and do not automatically upgrad to the new stable? -- hendrik
