It's not _just_ a library, it's a very special kind -- a runtime linker:

_[/tmp/try]_(vallor@lm)🐧_
$ touch foo
_[/tmp/try]_(vallor@lm)🐧_
$ /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 /bin/ls
foo
_[/tmp/try]_(vallor@lm)🐧_
$ /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 /bin/ls -l
total 0
-rw-rw-r-- 1 vallor vallor 0 Apr 25 04:40 foo

 ...know any other (mere) library that does that?
