<falconindy> kay: just curious -- it looks like nodes created by udev from
modules.devname all have 000 perms, and there's nothing in udev that attempts
to change this. is it intended?

<kay> falconindy: we might miss the default of 0600
<falconindy> seems like it
<kay> falconindy: stuff that has a rule works i guess
<kay> falconindy: i'll add the 0600 now
The filename parameter passed to mkdir can't contain anything but a
garbage value at this point. This was meant to be the full pathname to
the new udev DB, as the mkdir_parents() call before it won't create the
trailing child directory.
[replace mkdir_parents() + mkdir() with mkdir_p() -- kay]
Udev was the limiting factor for us on low-RAM systems.
Given an average RSS of 180kb, 128 workers would require ~23mb of RAM.
Now, please consider what happens when there is only, say, 15mb free.
Udev protects itself from OOM, and the kernel can do nothing but panic.
28 workers * 0.18mb = ~5mb. This change should not affect more powerful
systems much, given that they still get the addition from the amount of RAM.
This reverts commit 9b5af248f0.
Udev now explicitely labels only files/directories in /dev. The selinux
array API is not released and will not work on other distros at this moment.
systemd-udev is currently incorrectly labeling /run/udev/* content because it is
using selinux prefix labeling of /dev. This patch will allow systemd-udev to
use prefix labeling of /dev and /run.
Do not forget the leading "S" when appending the serial number,
otherwise we chop the last character of the model name.
