24// ProfileKeyedBaseFactory implementation for UserCloudPolicyManagerChromeOS
25// instances that initialize per-profile cloud policy settings on ChromeOS.
26//
27// UserCloudPolicyManagerChromeOS is handled different than other
28// ProfileKeyedServices because it is a dependency of PrefService. Therefore,
29// lifetime of instances is managed by Profile, Profile startup code invokes
30// CreateForProfile() explicitly, takes ownership, and the instance is only
31// deleted after PrefService destruction.
32//
33// TODO(mnissler): Remove the special lifetime management in favor of
34// PrefService directly depending on UserCloudPolicyManagerChromeOS once the
35// former has been converted to a ProfileKeyedService.
36// See also http://crbug.com/131843 and http://crbug.com/131844.
