Features:
+* when dissecting images, warn about unrecognized partition flags
+
+* honour specifiers in unit files that resolve to some very basic
+ /etc/os-release data, such as ID, VERSION_ID, BUILD_ID, VARIANT_ID.
+
* socket units: allow creating a udev monitor socket with ListenDevices= or so,
with matches, then actviate app thorugh that passing socket oveer
waitid() only on the children with the highest priority until one is waitable
and ignore all lower-prio ones from that point on
-* sd-event: drop stack allocated epoll_event buffer in sd_event_wait()
-
* maybe introduce xattrs that can be set on the root dir of the root fs
partition that declare the volatility mode to use the image in. Previously I
thought marking this via GPT partition flags but that's not ideal since
shouldn't operate in a volatile mode unless we got told so from a trusted
source.
-* look for /var/tmp automatically via gpt auto discovery
-
* figure out automatic partition discovery when combining writable root dir
with immutable /usr
"systemd-gdb" for attaching to the start-up of any system service in its
natural habitat.
-* maybe introduce gpt auto discovery for /var/tmp?
-
* maybe add gpt-partition-based user management: each user gets his own
LUKS-encrypted GPT partition with a new GPT type. A small nss module
enumerates users via udev partition enumeration. UIDs are assigned in a fixed
with stateless/read-only/verity-enabled root. (other idea: do this based on
loopback files in /home, without GPT involvement)
-* gpt-auto logic: introduce support for discovering /var matching an image. For
- that, use a partition type UUID that is hashed from the OS name (as encoded
- in /etc/os-release), the architecture, and 4 new bits from the gpt flags
- field of the root partition. This way can easily support multiple OS
- installations on the same GPT partition table, without problems with
- unmatched /var partitions.
-
* gpt-auto logic: related to the above, maybe support a "secondary" root
partition, that is mounted to / and is writable, and where the actual root's
/usr is mounted into.
* as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
-* in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
-
* figure out when we can use the coarse timers
* add "systemctl start -v foobar.service" that shows logs of a service
