# Options to pass to prelink
# -m	Try to conserve virtual memory by allowing overlapping
#	assigned virtual memory slots for libraries which
#	never appear together in one binary
# -R	Randomize virtual memory slot assignments for libraries.
#	This makes it slightly harder for various buffer overflow
#	attacks, since library addresses will be different on each
#	host using -R.

# How often should full prelink be run (in days)
# Normally, prelink will be run in quick mode, every
# $PRELINK_FULL_TIME_INTERVAL days it will be run
# in normal mode.  Comment this line out if prelink 
# should be run in normal mode always.

# How often should prelink run (in days) even if
# no packages have been upgraded via rpm.
# If $PRELINK_FULL_TIME_INTERVAL days have not elapsed
# yet since last normal mode prelinking, last
# quick mode prelinking happened less than
# $PRELINK_NONRPM_CHECK_INTERVAL days ago
# and no packages have been upgraded by rpm
# since last quick mode prelinking, prelink
# will not do anything.
# Change to
# PRELINK_NONRPM_CHECK_INTERVAL=0
# if you want to disable the rpm database timestamp
# check (especially if you don't use rpm/up2date/yum/apt-rpm
# exclusively to upgrade system libraries and/or binaries).
