Hi,
I have some spare space on my laptop (a rubbish Thinkpad E130) that
was originally meant for NetBSD, but I gave up on it due
suspend/resume not working.
This is how it looks from Debian:

Questions:
1) Can/should I reuse the EFI partition?
2) Can I reuse and mount the Linux swap partition?
3) I will nuke sda5 and install OpenBSD in there. Anything I need to
know or do before installation?
I have read the installation guide:
https://www.openbsd.org/faq/faq4.html#Multibooting
but it's quite short and terse.
Is multibooting worth it or is it just a pain in the down under? I did
install OpenBSD before but in a VM, so... apples and oranges really.
Thanks.
Hi,
Presumably you are using GRUB to multiboot. Yes you should keep the
EFI partition and add an OpenBSD directory in there, copy the
BOOTX64.EFI file to it (available on your local mirror in the 7.2/amd64
directory) and point your grub.cfg entry to the BOOTX64.EFI file in it.
It's easiest to edit the /etc/grub.d/40_custom file and add this:
menuentry 'OpenBSD/amd64 normal kernel' {
insmod part_gpt
insmod search_fs_uuid
insmod chain
chainloader (hd0,gpt2)/EFI/OpenBSD/BOOTX64.EFI
}
and run update-grub to modify grub.cfg.
Cheers,
Noth
