Bug#1040455: update-grub: when generating new grub.cfg entries from 40_custom not show as output on screen

[mh]

Package: grub-pc
Version: 2.06-14
Severity: important

Dear Maintainer,

* What led up to the situation?
executing "update-grub" (os-prober disabled!)

* What exactly did you do (or not do) that was effective (or
     ineffective)?
"update-grub" as root (os-prober disabled!)

* What was the outcome of this action?
On screen (xterm) I saw all the installed kernels of system grub was
  running from. In addition all bootable siduction-live.iso files were
  listed and appended to the list (due to a script in
  /etc/grub.d/60_fll-fromiso). The entries defined in
  /etc/grub.d/40_custom did not appear in this on screen list.

This leads  to the seemingly obvious conclusion they were not found or
honoured. Only further investigation will show they had been copied to
/boot/grub/grub.cfg .

This is confusing behaviour as the user expects to see the outcome of
his action, i.e. the *complete* final result on screen (xterm), not
only a part of a list which gives the impression something has gone
wrong.

* What outcome did you expect instead?
Show the complete list with all entries as copied to /boot/grub/grub.cfg

I classified it as "important" as this bug gives the user the
(wrong but convincing) impression of not successfully working!

(I accidentally booted a Debian-siduction kernel, not the pure Debian
Kernel. The bug is always the same)
