Description Ian Kent 2011-05-10 02:41:25 UTC 
Description of problem:

With an automount that has a key present in a file map and the same
key also present in an included map source, if the file map entry is
removed and a lookup is performed before a re-load is issued the
map lookup fails.

Version-Release number of selected component (if applicable):
autofs-5.0.5-31.el6

How reproducible:
Always.

Steps to Reproduce:
1. Create a file map, /etc/auto.includetest containing:
foo	localhost:/export/foo
+auto.test2

Create /etc/auto.test2 containing:
foo	<server>:/export/foo

Add an entry to the master map:
/includedtest		file:/etc/auto.includedtest


2. Perform a lookup on map key foo using "ls /includedtest/foo"
and wait for it to expire.

3. Remove map key from map /etc/auto.includetest and repeat
the lookup of step 2.
  
Actual results:
The lookup in step 3 fails to find the key in map
/etc/auto.test2.

Expected results:
The lookup in step 3 fails to find the key in map
/etc/auto.test2.

So, the original patch is actually needed although I'm
not completely convinced this won't have unexpected and
difficult to resolve side effects. But with so many
regression tests now I might be mistaken.
