See +\fBmachine-id\fR(5) +for more information about machine IDs\&. +.PP +This service is started after +local\-fs\&.target +in case +/etc/machine\-id +is a mount point of its own (usually from a memory file system such as +"tmpfs") and /etc is writable\&. The service will invoke +\fBsystemd\-machine\-id\-setup \-\-commit\fR, which writes the current transient machine ID to disk and unmount the +/etc/machine\-id +file in a race\-free manner to ensure that file is always valid and accessible for other processes\&. See +\fBsystemd-machine-id-setup\fR(1) +for details\&. +.PP +The main use case of this service are systems where +/etc/machine\-id +is read\-only and initially not initialized\&. In this case, the system manager will generate a transient machine ID file on a memory file system, and mount it over +/etc/machine\-id, during the early boot phase\&. This service is then invoked in a later boot phase, as soon as +/etc/ +has been remounted writable and the ID may thus be committed to disk to make it permanent\&. +.SH "SEE ALSO" +.PP +\fBsystemd\fR(1), +\fBsystemd-machine-id-setup\fR(1), +\fBmachine-id\fR(5), +\fBsystemd-firstboot\fR(1) |
