Hallo Carl, thx for the pointer. I fit in the group described with "conditions when you might want to consider using it" ;-) A feature I missed is "chainload". I wanted to chainload grub2, just to give it a try. "As I write (summer, 2018), the latest version is 6.0.3, and has not been updated since 2014, so it's beginning to look like it's been abandoned. " Looking at the git repo proves this comment wrong: https://repo.or.cz/syslinux.git/shortlog Obviously the author missed the 6.0.4 release (which has not been published in the news section of the syslinux homepage) Of course, grub's commit log looks much more impressive: http://git.savannah.gnu.org/cgit/grub.git/log/ Ingo Am 14.11.2018 um 17:09 schrieb Carl Karsten: > On Tue, Oct 23, 2018 at 11:32 AM Ingo Wichmann wrote: >> >> Hi Steve, >> >> Am 23.10.2018 um 15:04 schrieb Holger Levsen: >> Wow.

I've got a working setup with pxelinux. And I don't want to maintain a grub and a syslinux configuration, both. Most distros ship with isolinux as bootloader on the installer image. So it's easy to copy and paste the configuration to get the installer running on PXE. So until now I don't see any advantages moving to GRUB. Where do you see advantages in using GRUB for PXE?
