@ -18,8 +18,6 @@ Bugfixes:
str_split_quoted() should return a real return code, so spawn_child can
report the failure properly.
* udev_set_log_priority should verify the value before saving it.
External:
* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
@ -80,7 +78,7 @@ Features:
* maybe allow timer units with an empty Units= setting, so that they
can be used for resuming the system but nothing else.
* what to do about udev db binary stability for apps?
* what to do about udev db binary stability for apps? (raw access is not an option)
* maybe provide an API to allow migration of foreign PIDs into existing scopes.
