The Mandos system allows computers to have encrypted root file systems and at the same time be capable of remote or unattended reboots. The computers run a small client program in the initial RAM disk environment which will communicate with a server over a network. All network communication is encrypted using TLS. The clients are identified by the server using an OpenPGP key that is unique to each client. The server sends the clients an encrypted password. The encrypted password is decrypted by
Linux program for writing Microsoft compatible boot records. This program does the same as Microsoft "fdisk /mbr" to a hard disk or "sys d:" to a floppy or FAT32 partition except that it does not copy any system files, only the boot record is written.
uselessd is a systemd-208 fork optimized for less resource usage, a leaner DBUS ABI, fewer dependencies and BSD/Linux cross-platform compatibility. It reduces featuritis by constraining unit types and concentrating on system initialization and process supervision. In particular udev gets extracted to support alternative handlers, binary journald logging removed to allow established syslog services for early boot sequences. Some auxiliary reimplementations like systemd-fsck are transferred back t
