How or more importantly why are you using Ubuntu's grub2 in crux?
Is it an EFI system?  I'm not sure what you mean by UUID in the context of
fstab, I almost always have something like:

/dev/sdb1   /    ext4   defaults,noatime(or whatever)   0   1

I wouldn't recommend using utilities for a different distrobution, crux
comes with grub2.
