From plain looking at the code it looks o.k. to me
because as far as I see there cannot be regressions
for non-Slackware distributions.

@gozora
could you also review it because the changes are about EFI?

@wdmsde
many thanks for your valuable contributions to ReaR!

By the way, I have a question:
Your #1853 and this one
are about adding Slackware support in case of UEFI booting.
Do you know if ReaR works for Slackware when BIOS is used?

@jsmeix Thank you for considering my patches for inclusion. I have not tested with BIOS and had assumed that UEFI was a worst case. I do have other machines to test with and will try a BIOS config. Based on my experience so far I would guess it may only involve tweaks to grub or mkisofs in the BIOS specific logic.

I look forward to a pull request from you
with adaptions to support Slackware also on BIOS!
