I'm afraid that I'm not familiar with the SuS. Could you give me a URL
for this?

Unfortunately, it seems to break kernel compiles (for 2.2.13, at
least), if /bin/sh -> /bin/bash. Apparently some #define's are echo'd
to include/linux/compile.h, using the `-n' option. You can get around
this by using `make SHELL=/bin/bash ...' if compiling it directly, but
I don't think that works if going through make-kpkg.
