# According to this thread, these hooks should not be needed:
#  http://lists.freedesktop.org/archives/pm-utils/2008-November/001753.html
# #####  MOVED HOOKS
# 1. 50ntpd: ntp gracefully handles disappearing net on its own
# 2. 55battery: hal >0.5.10 handles this on its own
# 3. 90clock: Most systems should keep the hwclock in sync over a suspend /
#    resume cycle, and since this hook is a severe time waster otherwise,
#    we'll kill it.

mv $PKG/usr/lib/pm-utils/sleep.d/{50ntpd,55battery,90clock} \

# #####  REMOVED HOOKS
# 4. 65alsa: According to the alsa devs, this hook is useless.  Correct
#    way to workaround buggy alsa drivers is documented in README.SLACKWARE
#    http://lists.freedesktop.org/archives/pm-utils/2008-November/001808.html
# 5. 94cpufreq: all cpufreq governors are "sane" now, so this isn't needed
