In Ubuntu it's only used by obscure programs like gzip/gunzip/zcat,
kilall5/pidof, reboot/halt/poweroff, swapon/swapoff, all the lvm utilities...
(Did you know that even bash changes its behavior depending on whether it was
called as "bash" or as "sh"?)
Still, on the whole a very nice article. Possibly I should start an "articles
about BusyBox" section on the website...
