Hello Edward,

sorry for the late answer. I can not (I'm not allowed!) offer config data from any of the
lab's/bureaus computers, so I decided to check again the whole config, since several
boxes do as expected and others not (which is the weird part). I found a simple culprit:
somewhere in the near past, /etc/auto_master received an update and I simply have
overwritten the old one with the new one. So the autofs system never checked the exported
filessystem's list given by a mandatory /etc/auto_ext file and in the logical consequence,
no filesystem defined there was mounted.

After simply adding the missing line the mounting of the expected filesystems worked
again.

Kind regards,
Oliver
