Many thanks David - works perfectly! I can also understand where my
thinking was wrong.
For anyone googling this, here's a working example:
node default {
sysctl::config { "fs.file-max":
value => 65536,
comment => "Maximum number of filehandles",
}
}
class sysctl {
define config ($value, $comment) {
file { "/etc/sysctl.conf":
mode => 644,
owner => root,
group => root,
ensure => present,
}
augeas { "sysctl_$name":
context => "/files/etc/sysctl.conf",
changes => [
"set $name $value",
"insert #comment before $name",
"set #comment[last()] '$comment'"
],
onlyif => "get $name != $value",
notify => Exec["/sbin/sysctl -p"],
}
exec { "/sbin/sysctl -p":
subscribe => File["/etc/sysctl.conf"],
refreshonly => true,
}
}
}
Cheers,
Bryan
