No include of NIS maps in automounter maps possible any more?

No include of NIS maps in automounter maps possible any more?

[Frank Thommen]

Hi,

I hope this question is not too basic for this list, but I could not 
find any answer in the list archives or through friend google.

With automount version 4.1.3-187 (running on CentOS 4.4) I could have an 
automounter map (not auto.master) to be like:

key1   host1:/path1
key2   host2:/path2
+map.in.nis

This way I could add specific local mounts to a generally available NIS 
map or override NIS given keys with my own ones.

With automount 4.1.4-33 (on Fedora Core 5) this doesn't work any more. 
The additional map is simply ignored.  I tried with '+map.in.nis' and 
'+yp:map.in.nis' to no avail.

'automount' in nsswitch.conf is on 'files nis' in both cases.


Is this a bug or a wanted feature in 4.1.4?  Is there an other way to 
*combine* nis and local maps for automounting?  We have configured a lot 
of hosts with above setup and whith the current OS-updates this starts 
to break.


Any hints or pointers are appreciated.

Thanks you very much

    frank

I just posted some patches that implement this for 4.1.4.  Ian's
pretty busy with v5, so I'm not sure when they'll be included.  For
now, it's safe to rebuild your centos RPM on FC-5.

Well, you could use the multi-map syntax.  In auto.master, you would
have something like the following:

/foo  multi: file /etc/auto.foo -- yp map.in.nis

Thanks. Great solution.  It's pity the manpages don't mention it ;-)

The Fedora autofs is very close to the upstream autofs and plus map
inclusion and nsswitch integration is not present in version 4.

Jeff Moyer has done a lot of work on this and is working to push the
RHEL autofs patches upstream now. However, I'm still neck deep in fixing
version 5 bugs so it's a bit hard to get an update to version 4 out.

I think your only option at the moment is to use the RHEL or CentOS
version and exclude autofs from yum updates.

Doesn't matter what you put in nsswitch.conf.

Focus is version 5 at the moment and plus map inclusion and nsswitch
integration are standard features.

Get FC6 if you want to try out version 5.

No problem. The multi-map syntax as proposed by Jeff works perfectly and 
I'll stick with that for the time being.

I'll first sleep over it ;-)
