Linux+Solaris - NIS auto.master versus autofs5

Linux+Solaris - NIS auto.master versus autofs5

[David Mack]

I work in an environment in which Solaris and Linux machines NIS mount
the same automount maps, including auto.master. Typically,
/etc/auto.master just contains "+auto.master" on all of them.

With the advent of autofs5, this has started breaking. To get the
Linux machines running autofs5 to work, we've had to replace
/etc/auto.master with a version that looks something like this:

/volume yp:auto.vols
/system yp:auto.home
/local yp:auto.local
/homes yp:auto.homes
/home yp:auto.home
/xfn -xfn
/net -hosts             -nosuid

The NIS version (used by Solaris and older Linux machines) looks like this:

/volume auto.vols -intr,bg,tcp
/system auto.home
/local auto.local
/homes auto.homes -intr,bg,tcp
/home auto.home
/xfn -xfn
/net -hosts             -nosuid


Needless to say, I'm not wild about having to install a separate
/etc/auto.master on every new Linux machine.

It appears that the problem is that autofs5 doesn't like parameters
introduces with hyphens in auto.master, which Solaris unfortunately
requires.

Is there any way around this situation that will allow me to continue
to use a NIS-mounted auto.master on all of my machines?

I apologize if this was discussed to death a couple of years ago - I
looked in the archive and didn't find anything.

That should work fine.

Using the map type syntax is very version 4 and shouldn't be needed at
all by version 5.

And you shouldn't have to.

OK, I don't think that's correct.
Perhaps it has been fixed over time and I missed that I fixed it.

It is true that the man page specifies no "-" but I believe it is
accepted and works.

How about more information.
What version are you using?
How about a debug log?

And a quick test here confirms that this work for me even with a
relatively old verion 5.

Hi!

A late reply, but a similar thing has bitten me in the past:

With autofs5, it does honor settings in /etc/nsswitch.conf.
A line like

automount:      nis files

in there does tell autofs5 to lookup the maps first via nis, then via
files, so there shouldn't be a need to explicitly specify yp: maps in
the /etc/auto.master anymore so principially the old auto_master should
work?
