Description

I don't think this is a bug? In automountlocation-import operation we import all maps/keys that are in given /etc/auto.master file. However, mapping "/- auto.direct" was not in auto.master in the first case and thus it was not loaded. When you added the mapping "/- auto.direct" to /etc/auto.master, the import of auto.direct map worked. It seems inconsistent to me to import auto.direct file contents since it does not have a mapping in the imported auto.master file. After all, autofs didn't consider /etc/auto.direct when running from the local files either, did it? # cat /etc/auto.master /- /etc/auto.direct /ipashare /etc/auto.pune # ipa automountlocation-import pune /etc/auto.master ipa: ERROR: key /- already exists Since the error message is key "/-" already exists by default I removed "/- /etc/auto.direct" key from /etc/auto.master and tried importing again. Since the location already had the direct map in it created by default I expect /etc/auto.direct to be imported automatically. Ok, the error here is that the contents of a map were ignored if the map already existed in IPA. We should make an exception for auto.direct since we pre-create it in each location. The error is not that a file not mentioned in auto.master was not imported. What if there are already some automountkeys in auto.direct if we add the exception? We would have to either overwrite the old automountkeys or ignore the colliding imported ones. I think the rule now (and we're hitting it) is to ignore duplicates. So if we only ignore /- as a duplicate I think we'll be ok. Note that there can be multiple /- in an auto.master, we should handle that too. master: e856310d7512cafbb394dfdf861658dc6a81d93d ipa-2-1: 2e9d614cabfb556aedb6ca805593dfcf3fa811cd
