Comment # 4 on bug 1195850 from Giacomo Comes

One year has passed and nothing seems to have happened about this bug.
I decided to have a deeper look at the problem and found more information that
you may interested in.
1) The manual installation checkpoints list needs an update. It shows 50 points
in the documentation, but in the actual list 7 points seems to be gone replaced
by other 20. The order is different as well.
2) The hooks start to run in the inst-sys up to: before_switch_scr_finish.
Then after_switch_scr_finish and later hooks run in chroot.
Therefore the hooks executed up to before_switch_scr_finish runs fine out of
the box. A small trick allows to run later hooks as well.
I create the file: before_switch_scr_finish_00_fix_chroot.sh
which contains the line:
  cp /var/lib/YaST2/hooks/installation/* /mnt/var/lib/YaST2/hooks/installation
in this way the hooks present in inst-sys are present as well in chroot and can
be executed. The last hook to be executed in chroot should contain the line:
  rm -f /var/lib/YaST2/hooks/installation/*
May be this trick can be put in the documentation until the issue is fixed
properly.
