* tmpfs mounts automatically created by systemd (/tmp, /run, /dev/shm,
and others) now have a size and inode limits applied (50% of RAM for
- /tmp and /dev/shm, 10% of RAM for other mounts, etc.)
+ /tmp and /dev/shm, 10% of RAM for other mounts, etc.). Please note
+ that the implicit kernel default is 50% too, so there is no change
+ in the size limit for /tmp and /dev/shm.
* nss-mymachines lost support for resolution of users and groups, and
now only does resolution of hostnames. This functionality is now
now automatically set to "Y" at boot, in order to enable pstore
generation for collection with systemd-pstore.
- * A new 'hwdb' file has been added that collects information about PCI
- and USB devices that correctly support auto-suspend, on top of the
- databases for this we import from the ChromiumOS project. If you have
- a device that supports auto-suspend correctly and where it should be
- enabled by default, please submit a patch that adds it to the
- database (see /usr/lib/udev/hwdb.d/60-autosuspend.hwdb).
+ * We provide a set of udev rules to enable auto-suspend on PCI and USB
+ devices that were tested to currectly support it. Previously, this
+ was distributed as a set of udev rules, but has now been replaced by
+ by a set of hwdb entries (and a much shorter udev rule to take action
+ if the device modalias matches one of the new hwdb entries).
+
+ As before, entries are periodically imported from the database
+ maintained by the ChromiumOS project. If you have a device that
+ supports auto-suspend correctly and where it should be enabled by
+ default, please submit a patch that adds it to the database (see
+ /usr/lib/udev/hwdb.d/60-autosuspend.hwdb).
* systemd-udevd gained the new configuration option timeout_signal= as well
as a corresponding kernel command line option udev.timeout_signal=.
