How should local repo packages be bootstrapped after an upgrade?

[Sam Varshavchik]

I have a bunch of packages I build and maintain, which get installed from an  
internal createrepo-ed repo.

Normally, a new Fedora release that breaks binary ABI results in those  
packages being temporarily broken until I rebuild them on the new release,  
and ugprade them. Which is fine. Until now, fedup simply logged the broken  
dependencies that will exist after an upgrade, but it proceeds and updates  
all packaging to the new release. Afterwards, I just rebuilt and upgrade my  
packages, verify that everything is kosher with repoquery --unsatisfied, and  
close the books on the upgrade.

Looks like dnf has become a bit more combative, in F23.

It appears that dnf system-upgrade simply refused to update a bunch of  
packages, in order to preserve the binary ABI compatibility with my own  
packages. That's fine and dandy, but this leaves, apparently, no practical  
way to bootstrap my packages.

dnf distro-sync refuses to update the remaining system packages that system- 
upgrade skipped over, unless I use --allowerasing, which ends up removing my  
packages, in order for the upgrade to preserve all dependencies.

Now, after removing my packages, I can proceed and rebuild them, but I find  
this an extra hassle that's not really needed.

For the future, I'd like to know if there is a way to go back to the  
previous behavior, and proceed with an upgrade to a new release, and ignore  
broken dependencies of existing packages for which no update is available,  
at the time of the upgrade.
