thumby

A bootable thumbdrive image for rescue and maintenance.

• This is a proof of concept for PLL, s6-smj, and mdevd-as-an-admin.

• This is a general x86-64 kernel and root filesystem.

PLL

• It uses PLL to load the kernel with an internal initmpfs from partition one.

• The first time it boots, it will create a new partition three as an F2FS filesystem, consuming all free space on the drive.

• It then mounts the SquashFS filesystem in partition two as the lower, and partition three as the upper, of an OverlayFS, and mounts that as the new root.

• It then calls switch_root to boot into the new root.

s6-smj

• /usr/libexec/init then initializes /run, and 's6' is started as PID 1

• s6 initializes the rest of the system and starts daemons such as mdevd, mingetty and sshd.

mdevd-as-an-admin

• mdevd brings up the network and other media

USE

• the root password is thumby
