Finnix is a small, self-contained, bootable Linux CD distribution for system administrators, based on Debian testing. Today marks the release of version 91.0 for the x86/AMD64, PowerPC, and UML/Xen platforms.
Finnix 91.0 includes a new Linux kernel (2.6.24), automatic 32-bit/64-bit detection on the x86 platform, stackable RAID/LUKS/LVM detection and setup, and several bug fixes.
Automatic 32-bit/64-bit detection (x86)
If you press "enter" at the boot screen of Finnix 91.0 x86, the boot loader will now detect if you have a 64-bit capable CPU, and will load the appropriate kernel. You can still force 32-bit or 64-bit by entering the "finnix" or "finnix64" boot profiles. Note that this is for the x86 Finnix CD only; PowerPC G5 users will still have to enter the "finnix64" boot profile manually, as the yaboot boot loader does not have this capability.
While RAID, LUKS (encryption) and LVM detection have been in Finnix for awhile now, they were loaded in a certain order, and some configurations were not detected as a result. With Finnix 91.0, most configurations should be detected. For example, an encrypted LVM set on top of two RAID disks should be set up automatically.
While not a "major new feature", several bug fixes were made for Finnix 91.0, including LVM/LUKS fixes, and multiple-level /dev block device detection corrections.
