Hi Andreas,

Andreas Enge <andreas@enge.fr> skribis:

It just occurred to me: here nixbld1 and nixbld10 have the same UID,
which is wrong.  Can you check whether the others have a different UID?

Here I have:

nixbld1:x:30001:30000:Nix build user 1:/var/empty:/run/current-system/sw/sb=

You should fix it with something like:

  for b in `seq 1 10`; do usermod -u `expr 30000 + $b` nixbld$b ; done

Crossing fingers...
