# Rebuilding and customizing OneFileLinux (see https://github.com/zhovner/OneFileLinux/)

# The virtual machine provided by the author does not seem always available. This is an attempt to rebuild the OneFileLinux v0.3.2 without it.
# I chose Ubuntu 18.04 since its kernel version is close to the one used in OneFileLinux.
# Prerequisites might be at least:
sudo apt-get install git build-essential libelf-dev
git clone https://github.com/zhovner/OneFileLinux
cd OneFileLinux
# Error in build.sh if this is not done...
mkdir -p alpine-minirootfs/dev
# Error in build.sh if this is not done...
sudo mknod -m 600 alpine-minirootfs/dev/console c 5 1
# Th first time, it may give the error about System.map not found as in https://github.com/zhovner/OneFileLinux/issues/10 . We can comment the line "depmod -b ../$ROOTFS -F System.map $KERNELVERSION" in build.sh to make it succeed first, than uncomment it and run the script again...
./build.sh
# The script will should succeed and create OneFileLinux.efi, but when testing it on a computer various errors may appear. Maybe the information from https://github.com/zhovner/OneFileLinux/tree/master/FoxBuild should be followed also or instead...

# Instructions in https://github.com/zhovner/OneFileLinux/issues/14 might be useful, especially updated versions might be available at https://github.com/foxpdll/OneFileLinux/releases ...
# Also https://github.com/zhovner/OneFileLinux/compare/master...ankris812:OneFileLinux:master...
# https://github.com/n30f0x/OneFileLinux may provide a Dockerfile to build OneFileLinux, with an update kernel...
# https://github.com/zhovner/OneFileLinux/compare/master...coolcoder613eb:OneFileLinux:master seems updated with a newer kernel and Alpine Linux base version...

# Customizations
# Should edit /etc/inittab to launch commands at startup...?
# To get e.g. scripts from the boot USB drive:
#mount /dev/usbdisk /media/usb
# Ethernet network:
#ifconfig eth0 up
#udhcpc -i eth0
