@@ -24,6 +24,13 @@ Janitorial Clean-ups:
Features:
* Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
other doesn't. What a desaster. Probably to exclude it. Also
DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
numbers.
* port systemctl, systemd-inhibit, busctl, … over to format-table.[ch]'s table formatters
* pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
* add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
