Linux rescue disk
Each Linux distro can create a rescue disk
- generally not system specific
- could be CD-ROM, DVD, or USB device
- contains its own minimalist version of the kernel, key administration tools, and a shell
- Gives an admin the tools required to fix a broken system without re-installing
- allows for mounting filesystems on the system with or without entries in the /etc/fstab file
- utilities and tools included varies from version to version, but by mounting undamaged existing partitions, installed applications can also be accessed and used
