How crunkbong is made
Crunkbong is made from a debootstrapped devuan jessie. Unlike the miyo (devuan spin) method of taking an existing environment and modifying it with personalized tweaks, crunkbong is built from the ground-up. This ensures that every program that a developer wants is there, and nothing else. It is also more time consuming.
The following are some commands I used to build it. All of them are performed as root.
mkdir /wherever/crunkbong
deboostrap --arch amd64 devuan-base /wherever/crunkbong
crunkbong uses amd64 as its base for two reasons:
- Meltdown patches will likely never be available for i386. This message is straight from the KPTI patch developers.
- Most PCs nowadays, including many netbooks, are capable of running a 64-bit environment.
devuan-base is used instead of a full-on desktop environment. A typical minimal debootstrap will occupy something like 200mb, give or take.
I run the following commands to enter the chroot environment. From here, we can start building on the OS.
cd /wherever/crunkbong
mount -t proc proc .
mount -o bind /sys ./sys
mount -o bind /dev ./dev
chroot . /bin/sh
I run chroot sessions with sh instead of bash. I prefer this sh is more minimal. I've always found bash to be a bit sluggish in comparison.
One of the first things you want is packages, so begin installing them
*linux-image-amd64
*tshark and wireshark
*aircrack-ng and reaver
*wpa_supplicant
*nano
*tmux or dvtm
You should also determine whether or not your system will run X, or will be a minimal console session only.
This crunkbong script will pull proprietary firmware drivers into a folder in /home/crunkbong. A user may choose to install one during a live session using dpkg -i [firmware].deb. These are completely optional.
I run refractasnapshot to make a bootable, live ISO. I modify the configuration for highest compression, which produces a smaller iso.
rm -rf /tmp/*
refractasnapshot
Finally, I use dd to create a live usb drive:
dd if=/wherever/crunkbong/home/snapshots/[newestsnapshot].iso of=/dev/nameofyourdevice
