I've have both Ubuntu and Arch installed on my computer, and want to change the labels of the / and /home partitions (four in total), to make it clear which is which. Can this potentially break anything?The only thing that I can think of is /etc/fstab; this shouldn't be an issue in my case, since it defines partitions by UUID, not label.
Is there any danger in changing the labels of my hard drives?

Hard drives usually don't have labels, it's filesystems that do. Here are the main places where a filesystem label is likely to come up:In /etc/fstab.In your bootloader configuration (e.g. /boot/grub/grub.cfg). If your Grub configuration is automatically generated, run update-grub after changing your labels and verify that the result is what you wanted.Mostly for removable devices: in the configuration of automounting tools (in custom udev rules, as directory name under /media or /run/media/user_name (if not created on the fly), in /etc/pmount.*, in /etc/auto.misc and files referenced from /etc/auto.master, etc.).
