If you setup a schedule such that packages are only installed certain hours of
the day, well, that part works. They won't install until that time. However, if
you have a policy that depends on the package being installed, if it is NOT
installed due to the schedule, it satisfies the Require and everything else
happens. I'm going to call this misfeature: "No package? No Problem! ":(
Example: with this example, if you apply the policy after 8pm (if you are using
UTC like we are, that's noon PST) then it will actually install the
configuration files and attempt to start the service. This is clearly a bug.
Given some multi-application interactions, this could cause a major service
outage. (I didn't find this with snmp but instead with some inhouse system
components. I replicated it with this config before reporting it)
I observed this on 2.7.19 but checking the sources it appears likely to be a
problem with 3.0 as well.
site.pp:
# Schedule in the early part of the working day (not peak)
schedule { 'early-day':
range => '17 - 20',
period => daily,
periodmatch => number,
}
Package {
schedule => 'early-day',
}
node default {
class { snmpd: }
}
class snmpd {
package { 'net-snmp':
ensure => present,
alias => 'snmpd',
}
package { 'net-snmp-perl':
ensure => present,
require => Package['net-snmp'],
}

owner => root,

}

}
}
