- systemd
System and Service Manager systemd is a suite of basic building blocks for a Linux system It provides a system and service manager that runs as PID 1 and starts the rest of the system
- systemd-boot UEFI Boot Manager
systemd-boot reads simple and entirely generic boot loader configuration files; one file per boot loader entry to select from All files need to reside on the ESP
- systemd Optimizations
This still needs some love in systemd upstream to be a smooth ride, but we definitely would like to go this way sooner or later, even for the normal desktops Add an option for service units to temporarily bump the CPU and IO priority of the startup code of important services
- New Control Group Interfaces - systemd
Well, as mentioned above, a dependency network between objects, usable for propagation, combined with a powerful execution engine is basically what systemd is Since cgroups management requires precisely this it is an obvious choice to simply implement this in systemd itself
- systemd-resolved and VPNs
systemd-resolved service supports routing lookups for specific domains to specific interfaces This is useful for hooking up VPN software with systemd-resolved and making sure the exact right lookups end up on the VPN and on the other interfaces
- Frequently Asked Questions - systemd
A: The recommended way is to copy the service file from usr lib systemd system to etc systemd system and edit it there The latter directory takes precedence over the former, and rpm will never overwrite it
- Presets - systemd
systemd 32 and newer support package “preset” policies These encode which units shall be enabled by default when they are installed, and which units shall not be enabled
- Running Services After the Network Is Up - systemd
Its primary purpose is for ordering things properly at shutdown: since the shutdown ordering of units in systemd is the reverse of the startup ordering, any unit that has After=network target can be sure that it is stopped before the network is shut down when the system is going down
