It is rare that I login as a user then su to root in Console.  I do that
all the time tho when in KDE.  KDE no longer allows a person to login as
root and I think it is a good idea as well.  So, when I need to emerge
something, edit a config file or do other things as root, then su or
kdesu comes in handy.  ;-)   I am able to open about anything as root if
needed.  Konsole and some sort of file manager, Konqueror or Krusaderm
is my biggest tools.

I have never had /dev in fstab that I recall.  I also removed all the
things that were commented out since they should be ignored anyway.   I
have a lot of old lines that are no longer needed, CD drive, old
partitions and such.

Got that added.   Let me know what to look for.  Right now I plan to use
nox so that I can look for myself, since boo boos are not logged to
dmesg or messages.

I don't use the quiet or the splash stuff.  I like it simple remember?
I watch the stuff scroll up and that is how I saw the errors posted.  If
I wasn't watching real close, I would have never noticed them since I
was using dmesg, messages and grep.

I have ls aliased to ls -al.  You noticed huh?  lol

I can't show that because it won't let me get that far.  When I tell
Krusader to open as root, a pop up window comes up and asks for the root
password.  When I type in the password, it complains about su not being
in the path or missing then goes away.  So, I can't post that one.

That said, I did a mount >> <some file> and then did the same while
booted without the init thingy.  Here it is then I'll explain.  Take
note of the / partition which is sda3 here:

The top one is while booted WITH the init thingy.  The bottom one is
while booted withOUT the init thingy.  You see the same differences I
see?  They are subtle but it is different.  It appears to my small mind
that the init thingy is not mounting / correctly.  Is dracut doing
something wrong?   There is a small difference in the devpts line but
not sure if it matters.

I'm still on the old grub.  I'm hoping to get this fixed then
repartition my stuff to use LVM then change grubs.  After that, maybe I
am good to go until someone breaks something else.  ;-)

I feel like I missed something.  If so, point it out to me.  I haven't
rebooted yet either.

Thanks.
