basic question on "key"

basic question on "key"

[es]

Hello there, I'm using autofs since a while and works very well.
Now I'd like to mount /home/milly and /home/es/Data from an NFS export. 
This means I cannot simply have /home in auto.master otherwise /home/es 
became inaccesible.
********* auto.master file
/home/milly  /etc/autofs/auto.home.milly
/home/es  /etc/autofs/auto.home.es
********* auto.home.milly
./              -fstype=nfs,rw          myhost:/home/milly

It seems I can't use ./ as key nor I can have /home/es in auto.master 
and have Data as key in auto.home.es because it will mount /home/es 
hidding the content of /home/es.

I have read trought the docs but can't find an example of this basic 
usage scenario.
TIA
Eli

Does this work (you'd need to use the modern autofs)?

** auto.master:
/home	/etc/autofs/auto.home

** /etc/autofs/auto.home:
milly	-rw	myhost:/home/milly
es -rw /Data -rw myhost:/home/es/Data

You might like to try a multi mount entry like

milly	myhost:/home/milly
es	/	myhost:/home/es	\
	/data	otherhost:/home/data

Note that multi mount map entries mount and umount all their entries as 
a single unit because of the cross filesystem issues that can arise. So in 
this case /home/es and /home/es/data would be mounted and umounted 
together.

And as Stephen says you need at least autofs version 4.0.0.
