  installpkg: prevent noise from the "stray cat" if tar hands it a broken
  pipe. Thanks to ivandi.
  Also (in the comments) provide a possibly better but untested solution.
  Thanks to SeB.
a/sysvinit-2.90-x86_64-2.txz:  Rebuilt.
  sysvinit-2.90 added an undocumented feature that tries to spawn agetty
  if it sees console= in the kernel command line. Avoiding the debate about
  whether this code belongs in init at all, at least such a change should
  be documented, and probably made opt-in. This patch disables the new
  behavior unless "sysvinit_agetty" is also seen in the kernel command line.
  It seems like this might have been something added for Hurd, and it might
  be wise to stick to what we've got rather than following upstream on this
  particular package. If anyone notices any other odd behavior, please let
  me know. Thanks to shastah.
a/sysvinit-scripts-2.1-noarch-19.txz:  Rebuilt.
  When checking for intel_pstate, direct the stderr to /dev/null in case
  the file doesn't exist in /sys. Thanks to ivandi.
  Allow forcing an option by editing /etc/default/cpufreq.

# rc.cpufreq: Settings for CPU frequency and voltage scaling in the kernel.
# For more information, see the kernel documentation in
# /usr/src/linux/Documentation/cpu-freq/
# Default CPU scaling governor to try. Some possible choices are:
# performance: The CPUfreq governor "performance" sets the CPU statically
# to the highest frequency within the borders of scaling_min_freq
# and scaling_max_freq.
# powersave: The CPUfreq governor "powersave" sets the CPU statically to the
# lowest frequency within the borders of scaling_min_freq and
# scaling_max_freq.
# userspace: The CPUfreq governor "userspace" allows the user, or any
# userspace program running with UID "root", to set the CPU to a
# specific frequency by making a sysfs file "scaling_setspeed"
# available in the CPU-device directory.
# ondemand: The CPUfreq governor "ondemand" sets the CPU depending on the
# current usage.
# conservative: The CPUfreq governor "conservative", much like the "ondemand"
# governor, sets the CPU depending on the current usage. It
# differs in behaviour in that it gracefully increases and
# decreases the CPU speed rather than jumping to max speed the
# moment there is any load on the CPU.
# schedutil: The CPUfreq governor "schedutil" aims at better integration with
# the Linux kernel scheduler. Load estimation is achieved through
# the scheduler's Per-Entity Load Tracking (PELT) mechanism, which
# also provides information about the recent load.
SCALING_GOVERNOR=ondemand
# For CPUs using intel_pstate, always use the performance governor. This also
# provides power savings on Intel processors while avoiding the ramp-up lag
# present when using the powersave governor (which is the default if ondemand
# is requested on these machines):
if [ "$(cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver 2> /dev/null)" = "intel_pstate" ]; then
SCALING_GOVERNOR="performance"
fi
# If rc.cpufreq is given an option, use it for the CPU scaling governor instead:
if [ ! -z "$1" -a "$1" != "start" ]; then
SCALING_GOVERNOR=$1
fi
# To force a particular option without having to edit this file, uncomment the
# line in /etc/default/cpufreq and edit it to select the desired option:
if [ -r /etc/default/cpufreq ]; then
. /etc/default/cpufreq
fi
# If you need to load a specific CPUFreq driver, load it here. Most likely you don't.
#/sbin/modprobe acpi-cpufreq
# Attempt to apply the CPU scaling governor setting. This may or may not
# actually override the default value depending on if the choice is supported
# by the architecture, processor, or underlying CPUFreq driver. For example,
# processors that use the Intel P-state driver will only be able to set
# performance or powersave here.
echo $SCALING_GOVERNOR | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor 1> /dev/null 2> /dev/null
# Report what CPU scaling governor is in use after applying the setting:
