Okay. So you want to use chattr +i to do this? If so, that would work
even if root installed a package, because root can't even overcome
immutability without explicitly running chattr -i on a file. So now, I
see no reason for an lfs user. Are there any other reasons for this
user? BTW, I've said before, but just to be clear to anyone who might
come across this thread mid-way, chattr is only for ext2/3, so it's use
requires limiting possibilities. Something one needs to watch out for
lest they get bitten by it.
To announce that there must be no criticism of the President or that we
are to stand by the President, right or wrong, is not only unpatriotic
and servile but it is morally treasonable to the American public.
