Suppose I've spent a bit of time configuring an RPi just the way I want, but then I need to make updates, both to the distro and to the installed software.
In this question, how to update is covered: How do I update software and firmware?
My question is more about what happens to my setup when I do the update:
Can I assume that an update to the distro won't cause anything to require re-installation/reconfiguration - i.e. updates will be largely transparent? (I'm using Debian Wheezy beta, but the same applies more widely).
In the case of third party software (for example Apache or whatever), is there any way that these can auto-update, or at least notify me of the availability of an update?
