Description-en: lock filesystems and write changes into RAM
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.
.
If the lockfs feature is enabled (in a configuration file, in the boot
commandline or by a heuristic), nothing will be written on the filesystems
listed in /etc/fstab, except for those that have been whitelisted, or for
the encrypted swap devices. More, bilibop-lockfs now is able to detect if
the drive has been locked by a physical switch, and then overrides its own
settings to unconditionally apply a 'hard' policy.
.
The root filesystem is locked (set readonly, using either aufs or overlay)
by an initramfs script which also modifies the temporary fstab to prepare
other filesystems to be locked later by a mount helper script.
.
bilibop-lockfs provides the following features:
* whitelist based policy: filesystems on which you want to allow persistent
changes must be explicitly listed in a configuration file.
* swap devices policy: they can be used 'as is', noauto, only if encrypted,
only if encrypted with a random key, or not used at all.
* not only filesystems are set read-only, but also block devices: this
forbids changes of the partition table, boot sectors, LUKS headers and
LVM metadata.
* plymouth messages to know at boot time if bilibop-lockfs is enabled or
not, or if an error occurred.
* desktop notifications at startup about filesystems status, to inform the
user that volatile or persistent changes are allowed or not, and where.
.
This package can be used as an alternative to fsprotect or overlayroot,
especially for writable operating systems embedded on a USB stick; but it
may also be installed on public or personal computers, for daily use,
kiosks, testing purposes, or as a tool in anti-forensics strategies.
