autofs init script doesn't support exclude

autofs init script doesn't support exclude

[Marc MERLIN]

From https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=91559

Could you add a patch of that sort so that we can override an ldap/yp
auto.master and mount one or several of those mountpoints locally in /etc/fstab?

I don't need this anymore as this is only useful if you use nis.
With ldap, you can use the following undocumented trick:
mrhat:~$ cat /etc/auto.master
/home /etc/auto.null
(doesn't work with YP though)

Thanks,

This would be /etc/default/autofs for Debian then ...

Yes, the fact that this can be different for different distributions means 
that it's not as straight forward as one would hope.

This is only one of the cases that needs to be catered. I'll take this on 
advisement but would prefer that these type of patches be carried in the 
distribution packages till we can deal with them in a sensible manner.

I'm not sure how to interpret this.  What do you forsee as "a sensible
manner?"  Do you think the mechanism is correct?  Is there a way to achieve
this with the Sun automounter?

I think this will need thought wrt what distros use which directories.
Perhaps some work on configure to make it happen right and at least a deal 
of work on the init script.

My question is "can we try to do this in a reasonably distribution 
independent manner". Having each distro carry its own patches is one way 
to identify the needs.

The reason I piped up here is that I have a crazy idea that it would be 
good to be able to use autofs in a range of distributions. Not just RedHat 
and Debian as it is now in the init script. But I'm not sure how I can do 
that yet.

A seperate configuration, such as is used in Linux, is not available with 
the Solaris automounter.

Actually I don't like this at all. The debian patches to the
init script of autofs3 are the reason why autofs4 is not even in
unstable yet: they are copious in size and fix some delicate
(shell coding, ldap) issues, so it's not obvious wheter they
need to be applied to the new init script and how these problems
are best fixed. Partly that's an issue of badly documented
patches, but they shoudln't have accumulated like this in the
first place.

What I'd much prefer to see (and actually thought about doing
myself) is removing the whole "plug the master map together" and
direct interaction with automount processes from the init
script. Instead there should be a autofscontrol tool (similar to
the ones for apache, bind, ntpd, etc; interactive operation is
not strictly a requirement though) which can start, stop, reload
and display status information. This would have to be able to
act globally on _all_ automount instances.

The init script could then stick to assuring a sane environment
and calling this control tool in the way desired by the user.

Separating distribution specific stuff from generic code would
be a first step towards that goal IMHO.
