We do, since this commit in 2016: https://sourceware.org/git/?p=cygwin-setup.git;a=commitdiff;h=f6d6c600edffdb83a57ed13384e38a504fdc366b However, it does only work if you pick by package and not by group and it has not yet been sufficiently tested to invoke auto-removal of such packages IMHO. If you're adventurous you could recognitize these packages as being installed as dependencies (maybe they already are, I have not checked) and then in libsolv use the SOLVER_CLEANDEPS flag for the solution so they can get removed if they are no longer part of a dependency chain that leads to an explicitly installed package. Setup has two command line options that somewhat deal with this problem, both of them were implemented before setup gained the capability mentioned above and none of them do directly what the OP was asking: The option --delete-orphans / -o removes packages installed on the system that are no longer available from the repository. The option --prune-install / -Y will remove _all_ packages except the ones that are explicitly requested via either --packages / -P or --categories / -C. I implemented this to enable up- and downgrading installations in unattended mode when that includes removal of packages, but that requires you to know the list of packages that you need to keep including their dependencies. I generate a new setup.ini with extra categories for this purpose (each of the categories contains all packages including dependencies for each type of install supported).
