Dualboot Devuan with FreeBSD
Well, Days ago I decided to give the Jump from Linux Mint 17.03, my main distro since 2015 to Devuan ASCII. In my last configuration I had installed FreeBSD, Windows7, and Haiku alongside Mint. To Install Devuan I decided to format all the HD and then adding the other OS. My first one was FreeBSD, but Devuan grub says it doesn't recognize the filesystem.
At the moment my /etc/grub.d/custom_40
menuentry 'FreeBSD' --class freebsd --class bsd --class os {
insmod part_msdos
insmod ufs2
set root="(hd0,msdos1,bsd1 >)"
kfreebsd /boot/loader
}
Perhaps the fourth or fifth combination I tried 
Another important data.

Re: Dualboot Devuan with FreeBSD
Hello
Read 12.2.1. The Boot Manager: https://www.freebsd.org/doc/handbook/bo … ction.html
I have done this but it was a while ago and it is all blurry now. I can tell you this:
1. Install Devuan first without GRUB
2. Then, install FreeBSD with boot0
This ought to do it. It is fairly easy as long as you don't install GRUB.

Re: Dualboot Devuan with FreeBSD
I dual-boot Devuan and FreeBSD...well, actually I multi-boot several Devuan-based distros and FreeBSD. The way that I did it may be unconventional though...
I reformatted my hardrive with all of the partitions that I knew I wanted. I formatted the partition that I wanted to use for FreeBSD as fat32 (which was /dev/sda3). I then installed my main OS on /dev/sda2 (/dev/sda1 is swap). I also used Grub.
Installed FreeBSD on the fat32 partition, and rebooted to my main OS. Added the following to the file /etc/grub.d/40_custom
menuentry "FreeBSD" {
set root='(hd0,3)'
chainloader +1
}Notice the (hd0,3) above...the 3 is the number of the partition that I installed FreeBSD on...your partition number may vary.
After adding that to the file, I saved and closed it. Then I ran...
update-grubRebooted, and FreeBSD was listed in the Grub. 
This worked well for me, but I don't know if it's the best method. 
Edited to add: I also chose UFS for my FreeBSD install rather than ZFS.

I have been Devuanated, and my practice in the art of Devuanism shall continue until my Devuanization is complete. Until then, I will strive to continue in my understanding of Devuanchology, Devuanprocity, and Devuanivity.
Veni, vidi, vici vdevuaned. I came, I saw, I Devuaned.

Re: Dualboot Devuan with FreeBSD
Hello astheroth. Check this nice tutorial: Dual booting Linux and FreeBSD. Good luck!
