}Well, if you want `insecure' mode, leave it as -1, and it won't bump

I am not sure what is your point. The secure level should do nothing
with Xserver AT ALL. The secure level is aimed to network ONLY.
I could not imagine if one is sitting at front of a server with the
console, the secure level is meaningful to this one. This person can
pick a hammer to break the entire machine; short the circiut; take out
the disk drive(s), and do whatever this one wants. The only prevention
for this problem is the key/lock/secure guard, not software.

My question is "why cannot the system let secure level stay at level 0
during the boot processing?" It can certainly be set to 0 after boot.
Would someone be happy to address this issue?

Thanks,
