I am not totally opposed to allowing /dev/null symlinks in .wants.d/ subdirs, and considering them a way to override dependencies. Such a "mask a dependency" concept would be OK. > I'd call this just "enabled". It follows the same "/etc/ trumps /usr" > schema that we have for udev rules, units, etc., i. e. an "enabled" > symlink should be allowed to live in /etc, /usr, and maybe even /run > (haven't though about whether this really makes sense, but perhaps for > full consistency it should be allowed). OK, let me get this right. You want an algorithm like this when somebody invokes "systemctl enable": a) if the unit file contains [Install], execute that, done b) if the unit file does not contain [Install], then delete any /dev/null symlinks in /etc/systemd/*.{wants,requires}.d/* of the same name. Then, "systemctl disable" should do this in your opinion: a) if the unit file contains [Install] remove all symlinks in /etc/systemd/*.{wants,requires}.d/* to it. b) if it doesn't, then *add* new symlinks to /dev/null in all .{wants,requires}.d/ directories where symlinks exist for it in /usr? Did I get this right? I am not convinced this is really a good idea though, as with this scheme package changes might reenable a unit that is otherwise disabled. Also, I kind like the fact that there's currently a clean error message generated when people try to disable a unit that is part of the OS itself. The scheme you propose would degrade that case to a NOP however, right?
