I’ve written a script to do that automatically.

I’ve improved the script so that it no longer requires any
parameters.  It finds the last-used setup.ini file and extracts the
list of currently-installed packages, all on its own.

This script has a couple of problems.  First, it doesn't take dependency
loops into account.  For example, if package p requires q and q requires
p, then both will be marked as non-root.  Second, if the mirror was used
for both an x86 and x86_64 installation, it always uses the x86
setup.ini, regardless of the current architecture.

The second problem is easy to fix. I think you can fix the first problem by using the dependency order computed by setup and recorded in /var/log/setup.log.full:

$ grep "Dependency order" /var/log/setup.log.full
Dependency order of packages: base-cygwin cygwin libdbus1_3 libiconv2 libintl8 libffi6 libpcre1 liblzma5 libgcc1 libstdc++6 terminfo...

You should only mark a package as a non-root if it is required by a package that occurs later in the list.
