# This is a simple script to generate an initial ramdisk when a new
# kernel is installed. If the kernel is vmlinuz-6.11.5, it will generate
# initrd-6.11.5.img. If there's a symlink pointing at the kernel (for
# example, vmlinuz-generic), it will also make a matching initrd-generic.img
# symlink. Finally, it also supports a plain initrd.gz symlink to the initrd,
# which might still be needed by some old setups.
#
# If you use an encrypted root, you'll need to make your initrd manually.
