Triple booting Windows/Debian/OpenBSD?

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:


Device Start End Sectors Size Type
/dev/sda1 2048 1023999 1021952 499M Windows recovery environment
/dev/sda2 1024000 1226751 202752 99M EFI System >>> [EFI
partition]
/dev/sda3 1226752 1259519 32768 16M Microsoft reserved
/dev/sda4 1259520 51845119 50585600 24.1G Microsoft basic data
/dev/sda5 51845120 124938239 73093120 34.9G NetBSD FFS
/dev/sda6 223012864 877277183 654264320 312G Microsoft basic data
/dev/sda7 206057472 223012863 16955392 8.1G Linux swap
/dev/sda8 877277184 976773119 99495936 47.4G Linux filesystem >>>
]Debian /home partition]
/dev/sda9 124938240 206057471 81119232 38.7G Linux filesystem >>>
[Debian / root]

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.
