LILO is the default bootloader, and it’s covered in slackdocs along with mkinitrd. The UEFI/GPT variant called ELILO is configured in an almost identical way, except that:

  • typing elilo does not configure it automatically - you must edit the elilo.conf file by hand.
  1. Make an initrd.gz file:

    sh /usr/share/mkinitrd/mkinitrd_command_generator.sh -l /boot/vmlinuz-generic
    • this will produce a long, ugly output… you need to re-write verbatim everything inside the single quotes ' (e.g. mkinitrd -c ... /boot/initrd.gz) in your terminal prompt.

    • hit enter and you’ll build an intrd.gz on /boot as indicated

  2. I’ve found (at least with encrypted drives):

    • the initrd.gz file needs to be placed here:

    • the desired kernel should be copied to the same place - I usually cp vmlinuz-generic

    • thus, the elilo.conf (also in this location) can be edited once and left alone even after kernel updates:

          append="root=/dev/rootpartition vga=normal ro"
    • I have had no problems with ELILO (old as it is) except with NVIDIA drivers. Using NVIDIA, after I launched an X graphical environment (i.e., my window manager), I was unable to return to a TTY, I had issues waking the device from sleep, and other problems. Using GRUB2 or rEFInd solved all of them. GRUB2 is included in the Slackware install iso.
