Package: autofs
Version: 5.1.2-4
Followup-For: Bug #598559
Dear Maintainer,
What led up to the situation?
Upgraded debian server from squeeze (6.0.3) running autofs 4.1.4+debian-3 to
stretch (9.7) running autofs 5.1.2-4.
What exactly did you do (or not do) that was effective (or ineffective)?
Retained existing /etc/auto* files.
What was the outcome of this action?
Error messages in syslog:
Mar 13 09:55:24 cronbot2 automount[701]: syntax error in map near [ -DDIR ]

Mar 13 09:55:24 cronbot2 systemd[1]: Started Automounts filesystems on
demand.
Mar 13 09:55:24 cronbot2 automount[701]: syntax error in map near [ u6 ]
Automount does not work on login.
What outcome did you expect instead?
I was hoping it would work and I could go home :).
I re-configured the /etc/auto.master not to use variable substitution, and
automount started working again.
The man page should eventually be updated--it still includes documentation for
the -D variable substitution option.
Thanks,
Bob
