new interface. In other cases loading the module is unwanted and
can lead to ill side effects. One such effect found is as follows:
"kldunload if_foo" tells the module to kill all its interfaces,
which results in messages sent to devd; the module unloads. Then
devd starts processing the messages, which ends up in a etc script
running ifconfig fooX, which reloads the module.

arrangement that has no intrinsic internal knowledge of whether devices
it is given are truly multipath devices. As such, this is a simplistic
approach, but still a useful one.
The basic approach is to (at present- this will change soon) use camcontrol
to find likely identical devices and and label the trailing sector of the
first one. This label contains both a full UUID and a name. The name is
what is presented in /dev/multipath, but the UUID is used as a true
distinguishor at g_taste time, thus making sure we don't have chaos
on a shared SAN where everyone names their data multipath as "Fred".
The first of N identical devices (and N *may* be 1!) becomes the active
path until a BIO request is failed with EIO or ENXIO. When this occurs,
the active disk is ripped away and the next in a list is picked to
(retry and) continue with.
During g_taste events new disks that meet the match criteria for existing
multipath geoms get added to the tail end of the list.
Thus, this active/passive setup actually does work for devices which
go away and come back, as do (now) mpt(4) and isp(4) SAN based disks.
There is still a lot to do to improve this- like about 5 of the 12
recommendations I've received about it, but it's been functional enough
for a while that it deserves a broader test base.

the restore program to restore all dumped extended attributes.
If the restore is running as root, it will always be able
to restore all extended attributes. If it is not running
as root, it makes a best effort to set them. Using the -v
command line flag or the `verbose' command in interactive
mode will display all the extended attributes being set on
files (and at the end on directories) that are being restored.
It will note any extended attributes that could not be set.
The extended attributes are placed on the dump image immediately
following each file's data. Older versions of restore can work
with the newer dump images. Old versions of restore will
correctly restore the file data and then (silently) skip
over the extended attribute data and proceed to the next file.
This resolves PR 93085 which will be closed once the code
has been MFC'ed.
Note that this code will not compile until these header
files have been updated: <protocols/dumprestore.h> and
<sys/extattr.h>.

The original DHCP specification includes a route option but it supports
only class-based routes. RFC3442 adds support for specifying the netmask
width for each static route. A variable length encoding is used to minimize
the size of this option.

This includes support for running a script to setup that directory.
The kenv variables init_chroot and init_script control this behavior,
