7 The account foolishly being "prevented" from bypassing SELinux is root.
8
9 So, configure a new kernel, disable SELinux, build, install, reboot.
10
11 Voila! No SELinux.
12
13 Or,
14
15 Edit grub.conf, reboot.
16
17 Voila! No SELinux.
18
19 Or, (as SELinux can be used to prevent access to grub.conf)
20
21 Just hit the damn power button and edit the kernel options in the grub command
22 line.
23
24 Voila! No SELinux.

26 Lessons learned:
27
28 Trying to prevent root from doing $STUFF on a pc is utterly and completely
29 pointless and simply will not succeed, ever. There is hardware where this can
30 be done, but it's not a PC, has no Intel designs in it and is often truly
31 secured with armed guards.
32
33 trying to prevent root from doing $STUFF on Unix is utterly and completely
34 pointless and simply will not succeed, ever. There are OSes where this can be
35 done, but they are not Unix. By definition, on Unix root can do anything,
36 including bypassing systems to prevent root from doing anything.
