We don't use shell scripts as much as most linux distros.
I fixed the bootscript to work with mksh and I'm now using it as my
/bin/sh. I'll see if I get any trouble because of that.
We also get a lower memory footprint and slightly shorter boot time (not
that the bootscript matters much for that, I guess).

Right. However, the bugs pointed out by coverity in bash are likely real
ones.

Like using both gcc2 and gcc4, this is likely to point more programming
errors in shell scripts. I'll make an optional package (not touching
/bin/sh for now) and do some tests to see what happens.
