There is no utility in splitting the OS in several partitions.
Might it make sense to have /usr mounted readonly except when upgradng

What could you fear which makes you want to keep /usr readonly.
software that isn't properly packaged as a .deb, but instead has an
"installer" that needs to be run as root.
If the installer must be run as root, it is precisely because it
needs to install software in /usr. You have an alternative: either mount
/usr readwrite and install it, or keep /usr readonly and not install it.
Keeping /usr readonly and trying to install the software has no chance
to work.
I have written such a software, called hopman. This discussion
suggests me that I should provide the option to install it in a user's
directory, without the need to be root, rather than install it system-wide.
software that is properly packaged, but has components that run as root
but do stuff with /usr outside my expectations.
Do you mean a package from a Debian repository which would install
a trojan horse in /usr?
