Here's a little something I finally got working at 2am last night. It
ensures an slist of specific mount points always have the noatime flag
(purely data folders in my case). If changes are made to the /etc/fstab
file, a remount of the affected partitions is performed.
Hopefully this can provide you with a basis to implement your specific
requirements :)

vars:
# our list of partitions to add the noatime flag to.
"noatime_partitions" slist => {"/data1","/data2"};
classes:
# only for specific hosts that match this regex pattern.
"do_it" or => { classmatch("qp.*"), classmatch("cr.*") };
files:
do_it::
"/etc/fstab"
edit_line =>
add_noatime_flag("noatime","4","$(noatime_partitions)"),
classes => if_repaired("fstab_updated");
commands:
# if fstab was updated, we need to perform a remount of the
affected
partitions.
fstab_updated::
"/bin/mount -oremount" args => "$(noatime_partitions)";
}
bundle edit_line add_noatime_flag(flag,field_num,partition)
{
field_edits:
"LABEL=$(partition).*"
edit_field =>
col("[\s]+","$(field_num)","$(flag)","append");
}
