I'm not talking about partitions ;-)

Neither was I. Force o' habit. May your partitions never be in random order.

According my faulty memory (I cannot reproduce it now)

section of config.scm:



  (bootloader
    (bootloader-configuration
      (bootloader grub-bootloader)
      (target "/dev/sda")
      (keyboard-layout keyboard-layout)))

/dev/sd<something> is what the Installer writes in the bootloader --8<---------------cut here---------------start------------->8---

I didn't realise that our *installer* did this… It shouldn't. Thanks for noting this.

So it's pure coincidence that grub-install on /dev/sda succeedes on the

whole set of machines users are installing via USB media? :-O

The odds may be hugely in your favour, but why gamble at all?

‘Pure coincidence’ is too loaded. It almost always works! But your original question already illustrates how ‘almost always works’ leads to false inductions of ‘should work’.

you've discovered, they aren't to be relied on, and you should use labels or UUIDs instead.

Labels and UUIDs are for volumes, not for the whole disk ;-)

Kind regards,

…? I must not be using the right terminology, but each drive has a ‘unique identifier’, and a human-readable label (if that human likes numbers, a lot) that isn't unique. ‘ID’ & ‘name’, then, fine, whatever we call it, my point remains :-P
