Note for distro maintainers: When writing sleep hooks, please consider adding any needed hooks to the package that requires the hooks, rather than pm-utils. An example would be if you distro wants anacron to run on resume -- the optimal fix would be to have the anacron package install a hook in /usr/lib/pm-utils/sleep.d that wakes anacron up on resume. This will also help package maintenance by allowing package maintainers to keep track of what the best way to handle any suspend/resume functionality their package requires insteas of leaving it up to the pm-utils maintainers to guess at what functionality is needed. To make this easier, pm-utils supports pkg-config, which makes it easy for packages that use automake to detect the presence of pm-utils and the locations that hooks should be installed in. The pm-utils pkgconfig file exports the following variables: pm_libdir: This is the directory that the pm-utils infrastructure is installed in. /usr/lib/pm-utils is the default value pm_sysconfdir: This is the directory that any package-specific pm-utils related config files should be installed in. Defaults to /etc/pm/config.d pm_sleephooks: This is the directory that sleep hooks are installed in. Defaults to ${pm_libdir}/sleep.d pm_powerhooks: This is the directory that power management hooks are installed in. Defaults to ${pm_libdir}/power.d pm_sleepmodules: This is the directory that sleep modules are installed in. Defaults to ${pm_libdir}/module.d
