If I do a base install to a new root:
setup-x86_64.exe --root "$(cygpath -wa .cygtest)" --no-admin \
--no-shortcuts --no-replaceonreboot --no-version-check \
--prune-install --verbose
And then run the same install again, I get:
libsolv: orphaned packages:
libsolv: base-0.0-0.any (erased)

libsolv:
Can't happen. No packagemeta for base
The "Can't happen" error results in all following transactions being skipped:
// Can't happen - throw an exception?
{
Log (LOG_PLAIN) << "Can't happen. No packagemeta for "
<< pv.Name() << endLog;
return;
}
This results in setup always showing no pending changes, even if you
have installed additional packages that should be pruned by
--prune-install, or if setup.ini has different contents.
The problem seems to be that we use SOLVER_ERASE jobs to remove all
non-base installed packages, and they take precedence over keeping the
pseudo-package 'base' installed.
Making the erase jobs weak seems to solve the problem:

However, I'm not sure if this is a good idea. Perhaps it should only be
done for pruned packages, and not explicitly uninstalled ones. I did try
various things to strengthen the requirement on 'base', but had no luck.
