We have also several very small automation & measurement devices in the
field which run a very dedicated more or less single application which
can be carefully audited.

In the OSADL safety working group, people are discussing about Linux for
safety critical applications. If we want to achieve such scenarios,
stripped-down systems are an absolute must.

Although increasing processor power even in embedded applications lead
to more and more standard-line kernels plus normal userspace components
(i.e. glibc instead of uclibc), there are still applications where the
final product consists only of the kernel plus the app, whereas during
development time, the system has a full-blown configuration.
