Theres two things you can protect, either the link to the file, or the actual
file. I see small, but finite value in protecting the link to the dynamic
linker. I do not see any value in protecting the actual dynamic linker.

The glibc spell points all symlinks in /lib elsewhere for the duration of the
PRE_INSTALL/INSTALL process, so you can remove the real linker, and any other
libs without problem. Part of the glibc bug wasnt just that removing the
linker
caused problems, some libraries have namespace conflicts so you end up with
half
the libraries with one version and half another and get conflicts, and of
course
that only showed up when upgrading to incompatible versions...anyways...

The linker symlink shouldnt be removed, of course, it shouldnt be tracked
either, so its almost a moot point. I'll leave it to the grimoire team to
decide
if they want to add a protected file for the various linker symlinks or not.

On a related note glibc PRE_INSTALL might be able to take advantage of
attempting to autodetect the dynamic loader, it could find a dynamic binary at
the start (anything in basesystem is fair game) and if it cant find one make a
note of it for debugging purposes and fallback to guessing like it does now.
But
again, thats for the grimoire team to decide on.
