Yes it is working great over here.  I am running 2.4.26 + trond's 
NFS_ALL + autofs4-20040417.
When I applied the patches there were no offsets or errors.

autofs-4.1 slow to mount

[Joseph Mack NA3T]

Linux-2.4.26, autofs4 as module, libc-2.3.2

mounting zip disk by autofs

with automount-4.0.0pre10, the disk mounts in 1sec

(interval between "attempting to mount entry /removable/zip"
and "kernel: kjournald starting. Commit interval 5 seconds"
messages)

with automount-4.1.2 the same interval is 11 secs.

on another similar machine, automount-4.1.2 won't mount
the zip disk, giving "e2fsck: need terminal for interactive repairs".
Running fsck from the command line shows a clean zip disk.
automount-4.0.0pre10 mounts zip disk OK.

Thanks Joe

Not sure what the issue here is.  Trying with my latest rpm would provide a
useful data point.  See below.

Hmm.  This second issue sounds like the spawnl issue discovered a little
while back.  Could you try the autofs package from my people page:

      http://people.redhat.com/~jmoyer/

Or, you could try the attached patch.

Thanks!

Jeff

Are you using the latest replicated server fixes patch?
This aounds like a problem that should have been fixed.
What does your map entry look like please?

Mmm. That's not good.

Do you get a message like
mouny(ext2) /path/to/mount : filesystem needs repair, won't mount

I'll see what I can find. I wonder what e2fsck is returning????

ah yes. I found it in syslog, I was looking at debug and messages and
didn't see it.

Thanks

OK I'll test out a similar format and see what I can come up with.

I'd like to know if you still get this message after doing what Jeff 
recommended.
