Package: libselinux1
Version: 2.4-1 and 2.3-2
Severity: normal
Tags: upstream
Dear Maintainer,
* What led up to the situation?
1) A panic in the kernel >=4.0 in the booting process
2) An line on the screen that was neither in the "kern.log" nor
"boot".
#
This error could be a cause for a panic in kernel-4.0, as it is caused
near this "place"
Some lines from the the screen (normal booting)
Freeing unused kernel memory: ...K (c...-c...)
Mount failed for selinuxfs on /sys/fs/selinux: No such file or directory
INIT: version 2.88. booting
Using kernel 4.0: (lines copied from the screen)
Freeing unused kernel memory: ...
general protection fault 0000 [#1]
Modules link in:
CPU=0 PID=1 comm=swapper Not tainted 4.0.4-2 #4
Hardware name ...
...
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
See a fix in the article "www.spinics.net/lists/selinux/msg16439.html"
with the subject "Mount procfs before checking /proc/filesystems"
The error is thus a logical one, caused by the usual non-thinking.
#
Why was that done?
How will the cause of the error be communicated to other, so they
could learn from it?
The general production of bugs (errors, especially logical ones) has
not decreased during the years. Why is that?

ones, is the toughest part of learning we must expect from that
system permanent mental damage for most students exposed to
it."

It is necessary to consider all consequences of
the proposed action in all states of nature.
There are lots of consequences of any given action. Many of the
problems of society today are at least partly due to the failure
to realize that the "obvious" action taken had so many bad side
effects.

There is a saying,
Any fool can learn from his own experience,
The wise man learns from the experience of others.
Too many students show that the first line is not correct.
But the second is very important, and is the basis of
the setting up of an educational program.
