There's a .config option when building Busybox: BusyBox 1.17.1 Configuration ────────────────────────────────────────────────────────────────────── ┌─────────────────────── exec prefers applets ───────────────────────┐ │ CONFIG_FEATURE_PREFER_APPLETS: │ │ │ │ This is an experimental option which directs applets about to │ │ call 'exec' to try and find an applicable busybox applet before │ │ searching the PATH. This is typically done by exec'ing │ │ /proc/self/exe. │ │ This may affect shell, find -exec, xargs and similar applets. │ │ They will use applets even if /bin/<applet> -> busybox link │ │ is missing (or is not a link to busybox). However, this causes │ │ problems in chroot jails without mounted /proc and with ps/top │ │ (command name can be shown as 'exe' for applets started this way). │ │ │ │ Symbol: FEATURE_PREFER_APPLETS [=n] │ │ Prompt: exec prefers applets │ │ Defined at Config.in:373 │ │ Location: │ │ -> Busybox Settings │ │ -> General Configuration │ ├────────────────────────────────────────────────────────────(100%)──┤ │ < Exit > │ └────────────────────────────────────────────────────────────────────┘ Not sure why exec'ing to a full path is a problem however. IIRC that overrode this behaviour. -- Stuart Longland (aka Redhatter, VK4MSL) .'''.
