Re: [systemd-devel] dbus activation service path

The D-Bus Specification[1] says: On Unix systems, the session bus should search for .service files in $XDG_DATA_DIRS/dbus-1/services as defined by the XDG Base Directory Specification. Implementations may also search additional locations, with a higher or lower priority than the XDG directories. so you should set the environment variables XDG_DATA_HOME and/or XDG_DATA_DIRS, the same way you set those variables to influence the search path for .desktop files. See [2] for more information. If a piece of software that reads session service definition files does not do this, please report that as a bug in that piece of software, using its bug tracking system. In particular, if you believe dbus-broker has a bug in this area, reporting it in flatpak's bug tracker is unlikely to get it seen or fixed by dbus-broker developers. smcv [1] https://dbus.freedesktop.org/doc/dbus-specification.html [2] https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
[systemd-devel] DevConf.CZ 2020 Systemd Meeting Notes
Hi everyone, Here are some notes from the systemd meeting we had before DevConf.CZ. We ran out of time before we could cover all the agenda items but I hope you'll find the content available useful! https://docs.google.com/document/d/1kXWfnVoYhiTyk4BaknDUde9vywi2lqd53Wu3bVYUMD0/edit?usp=sharing Anita ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
Re: [systemd-devel] elegant way to use a single mount unit file for multiple paths
Hi,
I’m not sure, but can’t systemd-tmpfiles get this sorted for you ?
See
https://www.freedesktop.org/software/systemd/man/systemd-tmpfiles-setup.service.html
Good luck :-)
