I have these lines (regarding linux compatibility)

options         COMPAT_LINUX
options         COMPAT_LINUX32  # req. COMPAT_LINUX and COMPAT_NETBSD32

and regarding EXEC_ELF I have these

options         EXEC_ELF32
###> options    EXEC_ELF64      # exec ELF binaries

It seems, from what I understand, that I have linux compatibility set
(for 32 bits and 64 bits). But I do not have the options set to run 64
bit ELF files. Would that be correct?

I have a linux executable that outputs these lines when I run this
executable through "file" (that is "file <file-name>").

ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically
linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.24,
not stripped

Can I run linux executables that are for 64 bit using compat_linux
when the /netbsd kernel is as configured above?
