I'm having trouble getting autofs working on a new install of Scientific Linux 7.2.
I have the files /etc/auto.master, /etc/auto/homes and /etc/auto.misc and /auto.direct setup, and they are copies of files on a working SL 6 machine. I can include the contents of the files at the end of this post.
When I log on as root on the just rebooted machine, directory listings don't show the directories I expected to see automounted.
If I do :
Code:
systemctl stop autofs
and then from the command line run
Code:
automount&
then I do see the directories mounted correctly.
If I then kill the automount process and run
Code:
systemctl start autofs
I can no longer see the directories, and the file /var/log/messages contains the lines below:

I think the relevant line here is

When automount is run from the command line, the /var/log/messages file does not contain this line :

Any idea why when run as a service, automount would not be able to read the auto.master file, but it can when run from command line ? I realize the second log excerpt also contains some error messages, but they don't seem to be affecting the functionality - the remote directories do get mounted correctly.
Not sure if it's relevant, but the permissions on the /etc/auto.master file are currently set to 600 and it is owned by root.
Thanks very much !
Bill
Contents of /etc/auto.master :
Code:
#
# Sample auto.master file
# This is a 'master' automounter map and it has the following format:
# mount-point [map-type[,format]:]map [options]
# For details of the format look at auto.master(5).
#
#/misc /etc/auto.misc
#
# NOTE: mounts done from a hosts map will be mounted with the
# "nosuid" and "nodev" options unless the "suid" and "dev"
# options are explicitly given.
#
#Maps for home folders
/Users /etc/auto.homes
# Direct maps
/- /etc/auto.direct

# Include central master map if it can be found using

# Note that if there are entries for /net or /misc (as
