/dev/disk/by-uuid does not exist

[Zoho Vignochi <zoho.vignochi@gmail.com>]

Hello,

I am running sid on a PPC (pegasos). After deciding to change my fstab
to use UUID (but then on second thought to labels instead) I read many
tutorials claiming that there should be a /dev/disk/by-uuid/ directory.
My system has only a by-path and by-id.

So I fired up my laptop which also runs sid (it is an x86) and lo and
behold /dev/disk/by-uuid was there. I do not remember doing anything
special to the laptop so my question is: Does anyone know a reason why
by-uuid wouldn't be created my ppc?
