Yes, I have that one enabled as well. Pretty much goes without saying since
FEATURE_SH_STANDALONE depends on: (MSH || LASH || HUSH || ASH) &&
FEATURE_PREFER_APPLETS

Here is what I get using your .config:


~/src/busybox-git$ PATH= ./busybox hush


BusyBox v1.17.0.git (2010-03-21 21:53:25 CET) hush - the humble shell

/home/simon/src/busybox-git $ cp        
hush: can't execute 'cp': No such file or directory
/home/simon/src/busybox-git $ fsck.minix
BusyBox v1.17.0.git (2010-03-21 21:53:25 CET) multi-call binary.

Usage: fsck.minix [-larvsmf] BLOCKDEV

/home/simon/src/busybox-git $ exec fsck.minix
hush: can't execute 'fsck.minix': No such file or directory
~/src/busybox-git$ 


No problem at all until I try to "exec" an applet that worked without "exec".
This only fails with hush, never ash, and only from commit
3ef4f77620a9f5f9a7c1247e29ea9c14e07b8a30 and onwards.
