On my laptop running Brigantia the first command takes 10s and recommends being run as root while "grep flags /proc/cpuinfo" takes 0.014s, so I would recommend the second command more for the speed difference (and for availability on non-Trisquel distros). > 2. Are those both absolute sure ways to figure it out? They show if the CPU declares x86-64 support, so it should be sure enough. > 3.

Just use "uname -m", check the flags only if it declares i686.
