No need to ship "enable *", btw. It's the implied default if no preset file is found or no matching line is found in them. Or in other words: the fedora default of "disable *" needs an explicit preset file, but the Debian default of "enable *" is actually the upstream default without preset file, too. > * This doesn't solve the problem of having these rather uninteresting > and cluttering symlinks in /etc at all; the wants.d symlinks would > still be as they are now, just the place that decides when to > enable them changes. If they are so uninteresting that there's no real benefit in allowing them to be modified, then I'd really recommend to simply ship the symlinks in /usr/lib, and not include an [Install] section. A lot of systemd's own units are like that. For example, since disabling udev or journald will only have the effect of making your system unbootable we don't ship [Install] sections for them, and instead hook them in statically. > I. e. my question is not so much about being able to restore the > default wants.d symlinks in /etc after a factory reset -- there are > multiple ways how this can be done: with presets or iterating over the > installed packages and re-enabling them (Debian also does some > house-keeping which unit files got enabled by postinstall scripts, > which can simply be replayed). Note that "systemctl preset-all" erally just iterates throught unit files that are installed and individually does the equivalent of "systemctl preset".

It's not a gazillion really. It's 15 or so on my laptop here...
