I thought about the MegaCli wrapper. It should be possible to make it read the name it was called by and then launch the respective program (i.e. symlink any to-be-wrapped command to /var/lib/glibcstuff ...)

that way you get along with one wrapper script and symlinks to it in /usr/bin.

Another thing I couldnt figure is if it's important to use all 32bit versions?

And the download links for archlinux are not working because they forward wget to an https url. maybe this is some limitation in the default wget version. If i figure it out i'll do updates on this.

this is my /usr/bin/MegaCli now, using a minimal Debian install in /debian.

#!/bin/bash

kernel.grsecurity.chroot_deny_chroot kernel.grsecurity.chroot_deny_fchdir \

for key in $KEYS ; do
   sysctl -w ${key}=0 1>/dev/null
done


export CHROOT=/debian
user=$(whoami)
if [ "$user" != "root" ];then
echo "This script needs root access"
exit
fi
mount -t proc proc $CHROOT/proc/
mount --bind /dev/ $CHROOT/dev/
mount --bind /sys/ $CHROOT/sys/
#we may need dev and maybe proc too to use this program
chroot $CHROOT /opt/MegaRAID/MegaCli/MegaCli $@
umount $CHROOT/proc
umount $CHROOT/dev
umount $CHROOT/sys

If you know how to relax grsecurity without using vanilla on Gentoo to allow PAM to not trigger a postinst error, you should edit the Gentoo section.
