Other Partition UUID

B

balanga

I'm trying to set up a Grub Menuentry for Super Grub2 according to these instructions

Code: 
menuentry "Super GRUB2 Disk" {
search --no-floppy --label boot --fs-uuid --set=root PUT-THE-UUID-PARTITION-HERE
set isofile=/boot/super_grub2_disk_hybrid_2.02s10-beta5.iso
loopback loop $isofile
configfile (loop)/boot/grub/loopback.cfg
}

Where, using FreeBSD, should I find the partition UUID? I'm assuming that the UUID would be the same under FreeBSD as Linux...
 
Look in /dev/gptid for the partition's UUID (or gpart list|fgrep uuid). But from that option --fs-uuid I guess you want the filesystem's UUID? That could be in the output of dumpfs(8) (for UFS) or zfs get guid <poolname/bootfs>.
EDIT P.S.: a zpool(8) also has an UUID.
 
Will I have a /dev/gptid on a Linux or FAT partition? or is there a place where all the UUIDs for all the partitions are stored?
 
I mainly use FreeBSD but I have Linux and Fat partitions...

I read somewhere that '-r' shows UUID but it looks like a lot of theses partitions have the same value, so that doesn't sound right.
 
That's the UUID of the partition type. Please look ls -l /dev/gptid.
man gpart|fgrep -- '-r'
Code: 
                   -r          Show raw partition type instead of symbolic
                               name.
