Hello Jim,

In your system are using CONFIG_INSTALL_APPLET_SCRIPT_WRAPPERS=y or
you using CONFIG_INSTALL_APPLET_SYMLINKS=y option?


If one compiles busybox with APPLET_SCRIPT option, the /bin/sh turns
out to be a file that has content #!/bin/busybox so when login is
invoked, the leading '-' to indicate its login invocation of shell is
lost.

If you are using APPLETT_SCRITP_WRAPPER option, would like to see
output of cat /bin/sh and see if there is some modification that is
made to that file.

Warm Regards,
-Sam
