[discuss] zoneadm detach - bug or painful feature changing mountpoint from legacy to

Tue, 01 Oct 2013 09:12:11 -0700

Just got bitten rebooting a different BE after detaching a zone as the mountpoint for the zbe tied to the current BE seems to be "changed" behind the scenes from 'legacy' to the configured '<zonepath>'.
Is this a bug (to be submitted) or rather a (not necessarily documented) feature? 

the following example best show the case (watch devzoneX):

richard@x3200:~# zoneadm list -cv

   0 global           running    /                              ipkg     shared
   - devzone          installed  /export/zone/devzone           ipkg     excl
   - devzoneX         installed  /export/zone/devzoneX          ipkg     excl
