The rootfs squashfs is already highly (XZ) compressed. Storing the applet messages in compressed form will increase the entropy and reduce the overall image compression ratio. Size diffs (compressed vs uncompressed): busybox (the executable): 364596 vs 384804 bytes. OpenWrt target images (the kernel image is unchanged, obviously): omnia-medkit-openwrt-mvebu-cortexa9-cznic_turris-omnia-initramfs.tar.gz: 9163597 vs 9162531 bytes (1066 bytes difference). openwrt-mvebu-cortexa9-cznic_turris-omnia-initramfs-kernel.bin: 9161688 vs 9160600 bytes (1088 bytes difference). openwrt-mvebu-cortexa9-cznic_turris-omnia-sysupgrade.img.gz: 9729550 vs 9729230 bytes (320 bytes difference). All in all, we save just a little bit over 1 kiB. As an added bonus, we also don't have to decompress the messages twice, (first from squashfs, then from the bzip2 message storage).

-----------------------------------------------------
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.
Sunshine!
