All the more reason to streamline the process...
why should everything take more time, just because some stuff must.

or just install ash and symlink sh -> ash
It makes a big difference on a slow machine, especially when

ash has an installed size of ~168k, and can result in commands being
executed faster than bash can be loaded up on a slow machine... well
