# usage

Choose an ARCHITECTURE in `mkimage-arch.sh` and set the corresponding
variable on top (for all practical purposes this should be 'pentium4').

Running `mkimage-arch.sh` builds a docker image named `archlinux32`
using the architecture packages picked above.

Running `uname -m` in the shell started with
`docker run -it archlinux32 /usr/bin/linux32 /bin/bash` indeed
shows `i486` or `i686` (Note: it shows `i686` for `i686` and `pentium4`,
also note that a docker chroot doesn't emulate CPU flags like SSE/SSE2 in
`/proc/cpuinfo`!).
