for it.
-systemd-udevd:
-
-* `$NET_NAMING_SCHEME=` – if set, takes a network naming scheme (i.e. one of
- "v238", "v239", "v240"…, or the special value "latest") as parameter. If
- specified udev's net_id builtin will follow the specified naming scheme when
- determining stable network interface names. This may be used to revert to
- naming schemes of older udev versions, in order to provide more stable naming
- across updates. This environment variable takes precedence over the kernel
- command line option `net.naming-scheme=`, except if the value is prefixed
- with `:` in which case the kernel command line option takes precedence, if it
- is specified as well.
-
* `$SYSTEMD_REBOOT_TO_FIRMWARE_SETUP` — if set overrides systemd-logind's
built-in EFI logic of requesting a reboot into the firmware. Takes a
boolean. If set to false the functionality is turned off entirely. If set to
hence synthesize drop-in snippets and symlinks for all boot entries at boot
or whenever they change if it wants to integrate with systemd-logind's APIs.
