Yes. mount --bind is a result of the major reworking the name lookup
machinery got between 2.2->2.4.

Well, as NEWS says:
autofs-4.0.0-pre10: Since autofs-4.0.0-pre9:
--------------------------------------------
* small fixes to make bind test more reliable
* NOTE: util-linux 2.10*p* is recommended for bind support
* fixed compilation problem in lookup_program (got rid of OPEN_MAX)
So, there really isn't much there. OPEN_MAX is the main reason I released
it. It was completely unnecessary, so I removed it. There is probably a
very slight performance increase, but I doubt you can measure it (select
is only looking at the range of fds which are actually interesting,
not everything from 0 to OPEN_MAX).
There are no real functional changes. If pre9 works for you, then pre10
will be the same.
