genfstab; -L or -U?

[Cloaked]

I'm currently installing Arch Linux on my laptop, and I have a question. I'm using a partition table with MBR, and the only guides I can find other than the official Arch install guide is made using a GPT table. The probem with this is that I need to run genfstab, but I don't know if I should use -L or -U for it.

Any and all comments and feedback will be greatly appreciated!

I recommend always using -U, labels can change and make the system unbootable.

-L will identify each disk with a label -U will identify each disk by UUID.

 

I would just run the following. Make sure you have your partitions mounted where you want them under /mnt.

• genfstab -U /mnt >> /mnt/etc/fstab

I personally prefer -L because it's human-readable and I can easily fix the labels if it ever changes.

The recommended is -U since the UUID is unique and won't change.

I never ever had the labels change on my laptops, even when changing distributions, so, in my experience, both are equally robust if you do not play around with the partition manager after the installation (I did not change the partitions when switching distributions).

Alright, thanks everyone. I went -U, and fingers crossed everything goes according to plan!
