Makes sense to me. However, I think we'd need to match the first
absolute path output from ldd because:
[EMAIL PROTECTED] ]$ ldd fool
linux-gate.so.1 => (0x009be000)
libc.so.6 => /lib/libc.so.6 (0x00b82000)
/lib/ld-linux.so.2 (0x00b65000)
So, how about the attached?
Ralph, the only linux that I have access to outside of TWW are debian 32
bit, and Fedora 32 bit, glad that your list is so much longer :)
