- The chroot technique is a valuable tool for repairing non-bootable Linux systems.
- It involves mounting a broken system's hard drive and tricking the current session into treating it as the root file system.
- Special system folders like /sys, /proc, and /dev from the live system are mounted into the new file structure.
- The process requires identifying the correct partitions for the root and /boot folders.
- Commands like `mount` and `chroot` are used to set up and enter the new file system environment.
- Once inside the chroot environment, system repair commands like `apt upgrade` or `dpkg-reconfigure` can be run.
- The technique was successfully used to repair a Nanopore GridION device by fixing broken symlinks and empty initrd.img files.
