+* systemd-repart: allow boolean option that ensures that if existing partition
+ doesn't exist within the configured size bounds the whole command fails. This
+ is useful to implement ESP vs. XBOOTLDR schemes in installers: have one set
+ of repart files for the case where ESP is large enough and one where it isn't
+ and XBOOTLDR is added in instead. Then apply the former first, and if it
+ fails to apply use the latter.
+
+* systemd-repart: add per-partition option to never reuse existing partition
+ and always create anew even if matching partition already exists.
+
+* systemd-repart: add per-partition option to fail if partition already exist,
+ i.e. is not added new. Similar, add option to fail if partition does not exist yet.
+
+* systemd-repart: add --size=auto for generating/resizing images of minimal
+ size, i.e. where the image file is sized exactly as large as necessary taking
+ SizeMin= into account, but not a single byte larger.
