# 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 KERNEL_SYMLINK is defined and points to a kernel, we'll use that.
# Otherwise, if KERNEL is defined and points to a kernel, we'll use that.
# Otherwise, if $1 is defined and points to a kernel, we'll use that.
# Example: geninitrd /boot/vmlinuz-6.11.6
# If none of these are true, we'll use the newest kernel we find in /boot.

# If you use an encrypted root, you may need an appropriate /etc/mkinitrd.conf
# (if you will be setting GENERATOR=mkinitrd in /etc/default/geninitrd), or you
# could try using GENERATOR=dracut.
