Autofs is failing: lookup(sss): setautomntent: No such file or directory

[Noah]

Hi,

I used to be able to automount the following directories just fine.

I can mount these nfs directories to non-ubuntu hosts.
A recent upgrade looks like it broke autofs.

Any clues what I can do to revitalize the mounts?

# cat /etc/auto.master
#
# 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
/-    auto.homenas
#
# 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.
#
#/net	-hosts
#
# Include /etc/auto.master.d/*.autofs
# To add an extra map using this mechanism you will need to add
# two configuration items - one /etc/auto.master.d/extra.autofs file
# (using the same line format as the auto.master file)
# and a separate mount map (e.g. /etc/auto.extra or an auto.extra NIS map)
# that is referred to by the extra.autofs file.
#
+dir:/etc/auto.master.d
#
# If you have fedfs set up and the related binaries, either
# built as part of autofs or installed from another package,
# uncomment this line to use the fedfs program map to access
# your fedfs mounts.
#/nfs4  /usr/sbin/fedfs-map-nfs4 nobind
#
# Include central master map if it can be found using
# nsswitch sources.
#
# Note that if there are entries for /net or /misc (as
# above) in the included master map any keys that are the
# same will not be seen as the first read key seen takes
# precedence.
