+ busybox --install [-s]
is almost good to go. Here is my work in progress. + Look at the FIXME in busybox.c to see what I need. The actual (sym)linking is disabled for now, although I'm sure it works ;) (Am I going to have to dig through /proc to find out where the currently running busybox is sitting?) + I put an #ifdef BB_FEATURE_INSTALLER around the new bits of code in busybox.c, and I have a #define BB_FEATURE_INSTALLER in busybox.def.h towards the bottom.
