ALT Linux Rescue
|ALT Linux Rescue|
ALT Linux Rescue is yet another sysadmin's Live CD with some forensic capabilities.
This weekly-updated image is intended to be text-only toolchest for analysis and recovery.
It will not try to use swaps or autodetect/mount filesystems unless requested explicitly.
Forensic mode is available via a separate boot target for BIOS users; UEFI users are asked to press F2 twice within boot manager menu and add "forensic" keyword to kernel commandline by hand as of 20140423. This will skip activating MDRAID/LVM too.
Build profile suitable for ALT Linux mkimage tool is included as .disk/profile.tgz.
X11-based software is being considered for an extended version.
i586 (BIOS) and x86_64 (BIOS/UEFI); SecureBoot might be left enabled in most occasions.
Two separate 32/64-bit hybrid ISO images suitable for direct writing onto USB Flash media (or CD-R by chance).
Hardening against rootfs spoofing has been implemented as of 20140423 (stage2 squashfs SHA256 check has been contributed by Maxim Suhanov); previous images are vulnerable to ISO9660-on-device containing a squashfs file with predefined name and specially crafted contents.
MDRAID/LVM2/swaps activation might occur with images before 20140416 or when booted via the default "Rescue" target; booting into "Forensic mode" will skip that (for both early userspace and final environment as of 20140416) and switch mount-system script to use ro,loop,noexec mount options (as of 20140423).
Physical device write blocking hasn't been considered so far.
