| I use much functionality in systemd that was not present in SysV init, and I really appreciate it. It has never crashed any OS that I have run. However, there are a few aspects of it that are inconvenient. Automount units use an unintuitive naming scheme, and you are not free to name them as you wish (as you might for a socket unit). If you are mounting an NFS volume immediately below the root directory, you don't see the problem, but if the mount is several directories deep and/or uses ASCII symbols (non-alphanumeric), it is not pretty. Socket units require two files per port. When I am moving complex inetd.conf setups to Linux, it's far easier to implement them with busybox inetd than convert dozens/hundreds of services to unit files, despite the increased functionality. Somebody has probably written some scripting to do this. I am not aware of any include directive for my own directories, so I don't have to place everything in /etc/systemd/system. There probably is a way to do this, and I am betraying my ignorance. And my, things can get messy in a hurry in /etc/systemd/system. I don't know how to configure users to be able to maintain their own (personal) units. And lastly, it's so seductive that I have no idea how to do many things in other operating systems that I easily do in Linux. I wish this itself was not a walled garden (but I'm not leaving). |
Systemd by default looks at a bunch of directories depending on the context.
$ systemd-analyze unit-paths (or --user / --global)
