Features:
-* network-wait-online should have a configurable timeout, maybe as --timeout-usec=
-
* The udev blkid built-in should expose a property that reflects
whether media was sensed in USB CF/SD card readers. This should then
be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
* timesyncd + resolved: add ugly bus calls to set NTP and DNS servers per-interface, for usage by NM
-* networkd-wait-online really should have a timeout by default
-
* add infrastructure to allocate dynamic/transient users and UID ranges, for use in user-namespaced containers, per-seat gdm login screens and gdm guest sessions
* machined: add an API so that libvirt-lxc can inform us about network interfaces being removed or added to an existing machine
more than once to ignore multiple network interfaces.
