Bilibop helps to maintain a debian gnu/linux operating system installed on an external media (usb, firewire, flash memory, esata). it hardens standard rules and policies to make the system more robust in this particular situation.

this package provides shell functions usable by other bilibop scripts on the running system or into the initramfs environment. these functions use /dev, /proc and /sys databases to output the drive name or the partition hosting the running system, and are fully usable by any unprivileged user or application. dm-crypt, lvm, loop devices, aufs and overlay root filesystems (and almost any combination of them) are supported. a 'drivemap' command is also provided, to show block devices in a tree of dependencies.

some features may require linux kernel 2.6.37 or higher to work properly.
