Want a cool new kernel feature but it won't show up in Debian for years?

make deb-pkg makes it easy to install a custom Linux kernel from source.

as root/sudo:

apt install build-essential libncurses5-dev gcc libssl-dev bc bison flex rsync libelf-dev
mkdir /usr/local/src/kernel
chown nonrootuser /usr/local/src/kernel
su - nonrootuser
