For details, see + systemd-backlight@.service8 + and + systemd-rfkill.service8. + + + + + + systemd.volatile= + + This parameter controls whether the system shall boot up in volatile mode. Takes a boolean argument, or + the special value state. If false (the default), normal boot mode is selected, the root + directory and /var are mounted as specified on the kernel command line or + /etc/fstab, or otherwise configured. If true, full state-less boot mode is selected. In + this case the root directory is mounted as volatile memory file system (tmpfs), and only + /usr is mounted from the file system configured as root device, in read-only mode. This + enables fully state-less boots were the vendor-supplied OS is used as shipped, with only default + configuration and no stored state in effect, as /etc and /var (as + well as all other resources shipped in the root file system) are reset at boot and lost on shutdown. If this + setting is set to state the root file system is mounted as usual, however + /var is mounted as a volatile memory file system (tmpfs), so that the + system boots up with the normal configuration applied, but all state reset at boot and lost at shutdown.
