  I am wrong here, as upgrades are performed as root to whom regular
read/write file permissions do not apply.  What I had in my mind was
what I actually use to protect public files in front-line servers, i.e.
running chattr +i on them.

  Still everything else does apply, mount options do much more than
preventing file modification, and I urge you to get a grasp of that
before you continue this debate.
