With FEATURE_SUID=y one can install busybox binary belonging to root with the suid bit set, enabling some applets to perform root-level operations even when run by ordinary users. Busybox then drops privileges for applets that don't need root access, before entering their main() function. Currently we don't install busybox binary with suid bit set, rendering this feature unusable. Note that we can't just "chmod u+s /bin/busybox" at runtime as a "cheaper" solution: it would waste approximately 200KiB of FLASH (the whole /bin/busybox binary gets copied into the overlay).

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
