ALT Linux Rescue is yet another sysadmin's Live CD.

Intro

This weekly-updated image is intended to be text-only recovery toolchest with some basic forensic capabilities.

It will not activate MDRAID/LVM when booted with "forensic" keyword (available via a separate isolinux boot target) and will not try to use swaps or autodetect/mount filesystems unless requested explicitly; mount-system script will use ro,loop mount options when booted in this mode.

Build profile suitable for ALT Linux mkimage tool is included as .disk/profile.tgz.

Tools included

Most of the usual rescue suspects should be there; biew, chntpw, dc3dd/dcfldd, foremost, john, md5deep, nmap, scalpel, sleuthkit, wipefreespace to name a few are available either.

Platforms

i586 (BIOS) and x86_64 (BIOS/UEFI); SecureBoot might be left enabled in most occasions.

Deliverables

Two separate 32/64-bit hybrid ISO images suitable for direct writing onto USB Flash media (or CD-R by chance).

Forensic issues

No hardening against rootfs spoofing in images before 20140423; implemented as of today (stage2 squashfs SHA256 check has been contributed by Maxim Suhanov).

MDRAID/LVM2/filesystems/swaps activation might occur in images before 20140416 or when booted via the default "Rescue" target; as of 20140416, booting into specially provided "Forensic mode" will skip that (both early userspace and final environment) while provided mount-system script will switch to use ro,loop mounts.

UEFI users: hashsum hasn't been propagated to refind configuration yet, and one has to press F2 twice within boot manager menu and add "forensic" keyword to kernel commandline by hand.

Device write blocking hasn't been considered so far.
