Busybox

There are certain differences between the normal Linux commands and those provided by BusyBox?. This also needs to be taken in account by mondo.

  • Busybox ps doesn't take options (solved in rev [792])
  • Output format for Busybox ps and normal ps auxww are different (especially process ID and user are inverted):
