of digital video recorders popular in Europe and Australia.
These devices have a USB client port which can be used to upload and
download recordings (and other files, such as MIPS binaries for execution
on the DVR's CPU) to/from their internal hard disk, in addition to some
other operations on files and directories.
These programs are no longer setuid, and now lock devices with flock,
not file locks in /var/spool/. They will no longer lock against UUCP
itself unless we modify UUCP to lock with flock, but this seems highly
unlikely to be an issue in the present day.
This means we can get rid of the suid/sgid parts of the code (which
have been removed). The program is now installed with normal permissions.
To prevent accidents, we now flock the tty line, attempting to get an
exclusive lock.

-false This primary always evaluates to false. This can be used follow-
ing a primary that caused the expression to be true to make the

This was brought up on the tech-userlevel list in October.
Using -fprint on findutils or new NetBSD find(1) does not do what
I wanted. For example, if saving results of all files that start
with a vowel or saving results of all files owned by group operator,
then the list of files owned by group operator would not include
the files starting with a vowel.
findutils's find has a workaround for this with -false and also a
"," comma opeator. (I made add this comma operator later; you can use
the comma to perform multiple independent tests.)
Instead, just add it to the list of files.

code) comes from findutils; it behaves the same.
From my manpage addition:
-fprint filename
This primary always evaluates to true. This creates filename or
overwrites the file if it already exists. The file is created at
startup. It writes the pathname of the current file to this
file, followed by a newline character. The file will be empty if
no files are matched.
Here is an example usage:
find /etc \( -name "*pass*" -fprint file1 \) -o \( -group operator -fprint file2 \) -o -name "w*"
Note that this example will NOT include entry in file2 if it is
matched in first expression. (This also is same behaviour as
findutils, and I have implemented a -false primary to handle that.
I will commit it later.)
This creates the file as command line argument parsing time.
If there is an error somewhere on that line, such as missing values
or mismatched parenthesis, then a file may still be created.
(Even if a later -fprint filename is unwritable.) This is similar
behaviour to findutils. (It has been suggested that this find could
be code to create the files in an extra stage after the command-line
argument parsing and before the actual function processing.)
I will add -fprintx and -fprint0 soon.

error out in a bit more friendly way when the user is trying to use
config(1) on a too old or too recent source tree.
To achieve that, introduce the "version NUMBER" statement which can be use
about anywhere in the config files. Also, use two defines, CONFIG_VERSION
(which is the actual version of binary), and CONFIG_MINVERSION, which is
the minimum version the binary supports.
Allowing a range of versions serves several purposes: first it allows me
to introduce the versioning without requiring it to be used right away in
the kernel tree, which means it will be possible to introduce new features
of config(1) rather progressively in the future. E.g., using 'no pci' in
a config file could only require the new version in that config file, so
that the rest remains compatible.
In the end, an actual bump of the main config system (i.e., in conf/files)
will only be required when e.g., ioconf.c semantics change.

no device at <attachment>
<attachment> can take two forms: either numbered/wildcarded, in which
case only exactly matching instances will be removed, or plain (with
no number or wildcard), in which case all matching instances will be
removed.
When <attachment> is a plain interface attribute, all instances using
that attribute (either directly or through an explicit device) will be
removed.
E.g.:
auich* at pci? dev ? function ?
audio0 at audiobus?
audio1 at auich?
audio* at auich0
no device at auich0 -> removes audio*
no device at auich? -> removes audio1
no device at auich -> removes audio1 _and_ audio*
no device at audiobus? -> removes audio0
no device at audiobus -> removes audio0, audio1 and audio*
no <device>
As in the previous case, <device> can either be numbered/starred, in
which case all exactly matching instances are removed, or plain, in
which case all instances of the device are removed.
E.g.: (continuing previous example)
no audio* -> removes 'audio* at auich0'
no audio -> removes all audio instances
track of instances attaching at root, and walk down the tree of active
device instances. Then, all instances that are not marked active are
found as orphans.
Doing it that way allows us to simply ignore orphan devices, instead of
warning about them and still keep them in the configuration. Now, orphaned
instances are considered as never having existed.
In the end, this allows 'no <device> at <attachment>' to be much more
efficient, as the user doesn't have to negate all descendents of the
instance s/he actually wants to negate. Warnings are still emitted,
though.
While there, make official a side-effect of the previous lack of action
against orphaned instances: config(1) used to warn about instances that
attach at a numbered device when no instance of that device with that
number existed, even though there was a starred instance of the device.
E.g. (provided by Alan Barrett):
pciide* at pci? dev ? function ? flags 0x0000
wdc0 at isa? port 0x1f0 irq 14 flags 0x00
wdc1 at isa? port 0x170 irq 15 flags 0x00
atabus* at ata?
wd0 at atabus0 drive 0
With this commit, config(1) will no longer warn about 'wd0 at atabus0'.
