Fedora 16 takes advantage of several new technologies to improve the speed, security and efficiency of the boot process:
Trusted Boot (tboot) is an open source, pre- kernel/Virtual Machine Manager module that uses Intel(R) Trusted Execution Technology (Intel(R) TXT) to perform a measured and verified launch of an OS kernel/VMM. It checks to make sure system files haven't been tampered with before letting the system boot, offering much greater protection against rootkits and other types of malware that try to cover their tracks by editing those files. Trusted Boot can be enabled at install, and will fall back to a normal boot if the hardware doesn't support it.
The GNU Grand Unified Bootloader (GRUB) receives a major update in Fedora 16. GRUB 2 allows better configuration options, better support for non x86 architectures, scripting and localization support. GRUB 2 has new configuration format and and files — please consult the GRUB manual for more information.
SysVinit scripts ported to systemd
Fedora 15 saw the introduction of systemd, a new system and service manager for Linux. The integration of systemd continues in Verne, with many more SysV init scripts converted to native systemd service files. The result is a faster, more efficient boot process and simpler service management.
