Whiteboard:
Fixed In Version: autofs-5.0.7-77.el7 Doc Type: Bug Fix
Doc Text:
Due to changes to the master map reading, master map entries were not being initialized properly when a map re-read was needed at startup. This happened due to a mismatch in the master map entry age that used to check if the entry needed to be updated. The entries were not updated properly. As a consequence, autofs ended up with non-functional or partially functional automount mounts. With this update, the master map is now properly read. As a result, the master map is correctly initialized and works correctly after startup.

How reproducible:
So far I've not been able to reproduce it

Steps to Reproduce:
