Admin-provided conditions · Perl 5.8.6
munki-
perls
Typed Munki perls for Macs from Tiger onward.
From G3 to M3, from G5 to M5, with Intel holding the middle: it’s all supported.
Six collectors
One native plist
02 / Method
Boring by design.
A condition should be interesting to the manifest and profoundly boring to the machine.
- Native values Foundation preserves booleans, numbers, arrays, and dictionaries as real plist types.
- Stock runtime Runs on Apple’s Perl 5.8.6 with no Python, package manager, or added ecosystem.
- Safe loading Plugins are ownership-checked, loaded in isolation, and skipped individually when broken.
- One clean write Results are collected, sidecar-locked, and atomically serialized to Munki’s conditional items.
03 / Catalog
Small answers.
Useful inventory.
One runner discovers a focused library of non-executable plugins. Each perl returns typed values; none carries its own plist machinery.
02
Security & management
FileVault, Gatekeeper, SIP, managed user state, Back to My Mac, enabled system extensions.
03
Hardware
Physical or virtual, with vendor identification for VMware, VirtualBox, and Parallels.
04
Upgrade paths
Hardware-aware eligibility from Leopard through Goldengate, sharing one reboot-scoped snapshot.
04 / Quickstart
Install.
Select.
Check in.
The package places the runner and its plugin library at /usr/local/munki/conditions.
Install the latest package
sudo /usr/sbin/installer \
-pkg munki-perls-0.1.N.pkg \
-target /Choose only the perls you need
Use managed org.munki.perls preferences, or place the same dictionary in perls/config.plist:
<?xml version="1.0" encoding="UTF-8"?>
<plist version="1.0">
<dict>
<key>included_perls</key>
<array>
<string>console_user</string>
<string>virtual_type.pl</string>
</array>
</dict>
</plist>Managed preferences take precedence. With neither selection source, every installed plugin runs.
05 / Release
One package.
No new runtime.
Runs on fully patched Mac OS X 10.4.11 Tiger and 10.5.8 Leopard on PowerPC, verified on real G5 hardware, all the way through the current release on the latest Apple Silicon. PowerPC, Intel, or Apple Silicon: it’s all supported.
