Systemd
v259 has been released. Notable changes include a new
'--empower' option for run0 that provides elevated
privileges to a user without switching to root, ability to propagate a
user's home directory into a VM with systemd-vmspawn, and
more. Support for System V service scripts has been deprecated, and
will be removed in v260. See the release notes for other changes,
