/dev/sda8               975.9M      1.3M    907.4M   0% /srv/ext

and then /dev/sda6 is available through /srv and /dev/sda8 through /srv/ext

I tried the following things in /etc/config/fstab for sda6 and sda8

  only specify mount[x].uuid=
  only specify mount[x].device=
  only specify mount[x].label=
  inverse config mount section order between sda6 and sda8

but sda8 is always mounted before sda6

In which order are processed the mount order from the /etc/config/fstab ?
It does not seems to follow the mount[$idx] order.

Kind Regards
