Some people wish to have updatedb only include mount points which are automatically mounted by "mount -a", which mounts devices listed in /etc/fstab. The following lines may be added to /etc/updatedb.conf to exclude non-automatic mount points from updatedb. Add before the "export PRUNEPATHS" line in /etc/updatedb.conf. # mount points not to be scanned (regexp matching lines into /etc/fstab) EXCLUDE_MOINT_POINTS=noauto EXCLUDE_PATH=`awk "/^#/ {next}; /$EXCLUDE_MOINT_POINTS/ {print \\$2}" < /etc/fstab | tr '\012' ' '` PRUNEPATHS="$PRUNEPATHS $EXCLUDE_PATH" This suggestion is due to Eric Delaunay > The problem is NOT > updatedb, rather it's actually caused by the "checksecurity" call in > /etc/cron.daily/standard. The easy fix for this is to mount your NFS > stuff nosuid and nodev so it ignores them.
