autofs5 variable substitution

autofs5 variable substitution

[Peter Bajurny]

I apologize if this is the wrong place for this, but my Googling has 
come up empty and I find myself at a loss.

In our enviroment we do automounts based on the OSNAME and OSREL 
variables.  With autofs4 and the sun automounter we manually specify the 
values of OSNAME and OSREL in the init scripts.  In the autofs4 init.d 
script there is a line for 'localoptions' where I can set '-DOSNAME=name 
-DOSREL=rel'.  But I can't for the life of me figure out how to set this 
with an autofs5 init script.  The init script specifies a confdir and 
the autofs file there.  I tried adding 'OPTIONS="-DOSNAME=name 
-DOSREL=rel"' to that line, and the automountd process started with 
those correct flags, but then it wasn't able to mount anything from my 
automount maps.  I also tried using LOCALOPTIONS instead of OPTIONS and 
that didn't do anything.

So I'm stuck.  Is there documentation somewhere on the configuration 
options I can pass to the init script?  Is what I'm trying to do 
possible anymore with autofs5

Thanks for the help,

Yes, the OPTIONS configuration entry probably needs a bit of explanation
in the comments.

See automount(8) or automount5(8), as the case may be, for the -O
option.

Use OPTIONS="-O -DOSNAME=name -DOSREL=rel".

Not sure about if you will need separate quotes around the options
themselves but give it a try.

Allright.  I've tried that, both with and without quotes around the
options.  In both cases the automount process ran with those options
according to ps, and 'normal' mounts worked, but I still couldn't access
our $OSNAME$OSREL mounts.  On my client, the default values of those
variables would lead to a mount of Linux2.6.28-18-generic.  I created
that mountpoint and tried to mount that, and not even that works.  I'm
wondering if I'm being hit with this bug filed on Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/autofs5/+bug/488229/
Although that but only affects user variables and not machine variables,
so I could be wrong.

If setting enviroment variables doesn't work, I can get around that by
using a combination of $OSNAME and $ARCH, but I'm worried that the
client isn't even using the default values properly.

Thanks,

Well now this is embarrassing.  It turns out all along that I had a
stale process that meant everytime I thought I was restarting autofs and
getting a new mount I was... not.  This is how we did the OPTIONS:
OPTIONS="-DOSNAME=ubuntuamd -DOSREL=1"

Thanks for the help Ian.

Of course, oops, my mistake, -D is in fact an automount option so that
is the way it should be done.
