Summary: Migration to managed hotplug events incomplete
Product: Linux From Scratch
Version: SVN
Platform: Other
OS/Version: Linux
Status: NEW
Severity: enhancement

Although the "udev" initscript now sets /proc/sys/kernel/hotplug
to /sbin/udevsend, there are a few more steps to do.
1) To avoid future incarnations of Bug 842 and prevent junk device nodes from
appearing in the real /dev (right now we just ignore them), add the following
commands to hotplug installation instructions:
rm /sbin/hotplug # because /sbin/udevsend does everything /sbin/hotplug did
sed -i s@/sbin/hotplug@/etc/hotplug/pci.agent@ /etc/hotplug/pci.rc
In "Short descriptions", remove the description of /sbin/hotplug, or, better,
replace it with the reference to udevsend.
2) On the udev page, optionally add the following command:
rm /etc/hotplug.d/default/10-udev.hotplug
That symlink is needed only in non-managed mode. In managed mode, if this
symlink is present, the following happens:
a) The kernel calls /sbin/udevsend in order to inform userspace about the
hotplug event
b) udevsend transfers that information to udevd
c) udevd calls handlers in /etc/dev.d and /etc/hotplug.d, including that
symlink
d) /sbin/udevsend is called again through that symlink. It detects a loop and
exits immediately.
Removal of that symlink optimizes things a bit by removing that loop.
