[Nook Color Android Development] HamNCheese:
A couple of suggestions:

* Some apps may expect su to reside in /system/xbiin - it would be a good idea to set a symlink here

* Busybox is rather useless without having all of its symlnks created. /system/xbin is an appropriate place for these. Something like this should suffice:

symlink("/system/bin/busybox", "/system/xbin/[", "/system/xbin/[[", "/system/xbin/arp", "/system/xbin/ash", "/system/xbin/awk", "/system/xbin/basename", "/system/xbin/bbconfig", "/system/xbin/brctl", "/system/xbin/bunzip2", "/system/xbin/bzcat", "/system/xbin/bzip2", "/system/xbin/cal", "/system/xbin/cat", "/system/xbin/catv", "/system/xbin/chgrp", "/system/xbin/chmod", "/system/xbin/chown", "/system/xbin/chroot", "/system/xbin/cksum", "/system/xbin/clear", "/system/xbin/cmp", "/system/xbin/cp", "/system/xbin/cpio", "/system/xbin/cut", "/system/xbin/date", "/system/xbin/dc", "/system/xbin/dd", "/system/xbin/depmod", "/system/xbin/devmem", "/system/xbin/df", "/system/xbin/diff", "/system/xbin/dirname", "/system/xbin/dmesg", "/system/xbin/dnsd", "/system/xbin/dos2unix", "/system/xbin/du", "/system/xbin/echo", "/system/xbin/ed", "/system/xbin/egrep", "/system/xbin/env", "/system/xbin/expr", "/system/xbin/false", "/system/xbin/fdisk", "/system/xbin/fgrep", "/system/xbin/find", "/system/xbin/fold", "/system/xbin/free", "/system/xbin/freeramdisk", "/system/xbin/fuser", "/system/xbin/getopt", "/system/xbin/grep", "/system/xbin/gunzip", "/system/xbin/gzip", "/system/xbin/head", "/system/xbin/hexdump", "/system/xbin/id", "/system/xbin/ifconfig", "/system/xbin/insmod", "/system/xbin/install", "/system/xbin/ip", "/system/xbin/kill", "/system/xbin/killall", "/system/xbin/killall5", "/system/xbin/length", "/system/xbin/less", "/system/xbin/ln", "/system/xbin/losetup", "/system/xbin/ls", "/system/xbin/lsmod", "/system/xbin/lspci", "/system/xbin/lsusb", "/system/xbin/lzop", "/system/xbin/lzopcat", "/system/xbin/md5sum", "/system/xbin/mkdir", "/system/xbin/mke2fs", "/system/xbin/mkfifo", "/system/xbin/mkfs.ext2", "/system/xbin/mknod", "/system/xbin/mkswap", "/system/xbin/mktemp", "/system/xbin/modprobe", "/system/xbin/more", "/system/xbin/mount", "/system/xbin/mountpoint", "/system/xbin/mv", "/system/xbin/netstat", "/system/xbin/nice", "/system/xbin/nohup", "/system/xbin/nslookup", "/system/xbin/ntpd", "/system/xbin/od", "/system/xbin/patch", "/system/xbin/pgrep", "/system/xbin/pidof", "/system/xbin/ping", "/system/xbin/pkill", "/system/xbin/printenv", "/system/xbin/printf", "/system/xbin/ps", "/system/xbin/pwd", "/system/xbin/rdev", "/system/xbin/readlink", "/system/xbin/realpath", "/system/xbin/renice", "/system/xbin/reset", "/system/xbin/rm", "/system/xbin/rmdir", "/system/xbin/rmmod", "/system/xbin/route", "/system/xbin/run-parts", "/system/xbin/sed", "/system/xbin/seq", "/system/xbin/setsid", "/system/xbin/sh", "/system/xbin/sha1sum", "/system/xbin/sha256sum", "/system/xbin/sha512sum", "/system/xbin/sleep", "/system/xbin/sort", "/system/xbin/split", "/system/xbin/stat", "/system/xbin/strings", "/system/xbin/stty", "/system/xbin/swapoff", "/system/xbin/swapon", "/system/xbin/sync", "/system/xbin/sysctl", "/system/xbin/tac", "/system/xbin/tail", "/system/xbin/tar", "/system/xbin/tee", "/system/xbin/telnet", "/system/xbin/test", "/system/xbin/tftp", "/system/xbin/time", "/system/xbin/top", "/system/xbin/touch", "/system/xbin/tr", "/system/xbin/traceroute", "/system/xbin/true", "/system/xbin/tty", "/system/xbin/tune2fs", "/system/xbin/umount", "/system/xbin/uname", "/system/xbin/uniq", "/system/xbin/unix2dos", "/system/xbin/unlzop", "/system/xbin/unzip", "/system/xbin/uptime", "/system/xbin/usleep", "/system/xbin/uudecode", "/system/xbin/uuencode", "/system/xbin/vi", "/system/xbin/watch", "/system/xbin/wc", "/system/xbin/wget", "/system/xbin/which", "/system/xbin/whoami", "/system/xbin/xargs", "/system/xbin/yes", "/system/xbin/zcat");
