Hello,
For your information, here is the modified autofs script that I have tested
on a RedHat 5.1 workstation in a an environment with Sun NIS servers. The
default script does not work in that case.
Except for some cosmetic modifications, the intent was:
- If a local master map does exist, do not read the NIS master map.
Indeed, the NIS master map cannot be understood because it uses
options Solaris can understand but automount cannot (such as direct
mounts). Default script merges both master maps if they exist. Is
this useful?
- In the case of a local master.map, try to read NIS secondary maps.
For example, I was interested in reading the NIS auto.home map,
although I had to install a local /etc/auto.master map for the
above reasons.
I hope this script can be of some help... If someone wants to include
such modifications to the autofs package, I'd all too happy to help.
