>+# *sigh*, I hate this, but theres not another good way to do it.
>+# kexec needs zlib to handle/load compressed kernel files, it also
>+# needs to be able to reboot the system after everything has been unmounted
>+# This presents a problem, since zlib is located in /usr/lib/libz.so.
>+# The only real solutions we have are:
>+# 1) statically link against zlib 
>+# 2) write a separate statically linked utility
>+# I don't like either solution, especiatlly since Fedora has mandated dynamic
>+# but it seems like (1) is the easiest way forward.  Unfortunatley the config
>+# script automatically adds -lz to everything, so to work around that, I have
>+# to:
>+# a) export LIBS="-Wl,-Bstatic -lz -Wl,-Bdynamic"
>+# b) configure --without-zlib
>+# This is rather horrendous, but whatever, kexec is always last on anyones
>+# mind ayway
