# Motivation: DMG files provide a true HFS file system
|
|
# and are easier to manage and .pkg bundles.
|
|
#
|
|
# Note: the 'apple' Provider checks for the package name
|
|
# in /L/Receipts. Since we install multiple pkg's from a single
|
|
# source, we treat the source .pkg.dmg file as the package name.
|
|
# As a result, we store installed .pkg.dmg file names
|
|
# in /var/db/.puppet_pkgdmg_installed_<name>
