A portion of my autofs class:
class autofs {
package { autofs: ensure => installed }
# Only update /etc/auto.master if it doesn't exist, or if it has the same
# contents as the original package install. Ie. do not overwrite user changes
# to the file.
# Compute the sha hash of the current file, and the original template, to see if
# the file has changed. It it has, set "replace" to no. /dev/null is used to
# prevent exceptions when the files don't exist (if /dev/null doesn't exist, we
# can assume we are f$cked)
$tmp_a = sha1(file("/etc/auto.master", "/dev/null"))
$tmp_b = sha1(file("/usr/share/autofs/conffiles/auto.master", "/dev/null"))
if $tmp_a == $tmp_b {
$replace_master = yes
} else {
$replace_master = no
}
rootfile { "/etc/auto.master":
replace => $replace_master,
source => "autofs/auto.master"
}
}
