How to migrate drive content

This procedure explain how to migrate the content of one internal drive to another (example: upgrading your hard disk for a SSD), without requiring more than one SATA port (so the procedure works on laptops).

Note: This procedure works well if using a MBR. On the other hand, GPTs are more complex so we can not just copy them as-is: we have to recreate the headers. This implies that with GPTs, some systems may become unbootable (until some setting are changed manually) because IDs have changed.

WARNING: Some steps might assume 512 octets sectors.

Requirements

• A LiveCD/LiveDVD/LiveUSB of Linux with GParted, kpartx and all the necessary driver to manage the partitions present on the old drive.
• An external drive with enough free space to hold a single file which size equals the capacity of the old internal drive. Note: A contiguous unallocated zone maybe used in place of a file, but it’s more complex and error-prone.

#! /bin/bash

# A thin wrapper over the Nit’s `./tests.sh` script that displays the changes
# since the last run.
#
# Also, recompiles (except when `--no-make` is specified) the invoked engine
# before running the tests.
#
# Synopsis
# --------

jcbrinfo

#! /bin/sh

# dirname <path>
#
# Strip the last path component.
#
# Apply the same transformation than `dirname(1)`, but end the resulting path
# with `/`, so it can be safely used inside a `"$(…)"`
#
# Edge cases
