Subject: How can I assess compatibility of a statically linked binary?


when I have a file linked against glibc the file(1) utility will usually
tell me something like this:

ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked
(uses shared libs), for GNU/Linux 2.6.15, stripped

However, when I run this on a statically linked binary that uses musl, I

ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked,

which gives no indication of the minimum expected kernel. Does that mean
that this binary will also run on, say, a 2.4.x kernel? I guess not?

How can I tell which kernel interface a certain binary requires? After
all the system call numbers on which the libc relies change every once
in a while.
