* What led up to the situation?
Checking for defects with a new version
test-[g|n]roff -mandoc -t -K utf8 -rF0 -rHY=0 -rCHECKSTYLE=10 -ww -z < "man

[Use "groff -e ' $' -e '\\~$' <file>" to find obvious trailing spaces.]
["test-groff" is a script in the repository for "groff"; is not shipped]

[The fate of "test-nroff" was decided in groff bug #55941.]
* What was the outcome of this action?

Wrong distance between sentences in the input file.
Separate the sentences and subordinate clauses; each begins on a new
line. See man-pages(7) ("Conventions for source file layout") and
"info groff" ("Input Conventions").
The best procedure is to always start a new sentence on a new line,
at least, if you are typing on a computer.
Remember coding: Only one command ("sentence") on each (logical) line.
E-mail: Easier to quote exactly the relevant lines.
Generally: Easier to edit the sentence.
Patches: Less unaffected text.
Search for two adjacent words is easier, when they belong to the same line,
and the same phrase.
The amount of space between sentences in the output can then be
controlled with the ".ss" request.
Mark a final abbreviation point as such by suffixing it with "\&".
Some sentences (etc.) do not begin on a new line.

The number of lines affected can be too large to be in a patch.

556:This method may be used to obtain an address via DHCP with any of the
tools: dhclient, udhcpc, dhcpcd. (They have been listed in their order of
precedence.) If you have a complicated DHCP setup you should note that some of
these clients use their own configuration files and do not obtain their
configuration information via \fBifup\fP.
595:This method is used to create GRE or IPIP tunnels. You need to have the

IPv6 addresses. Using this method on its own doesn't mean that RDNSS options
will be applied, too. To make this happen, \fBrdnssd\fP daemon must be
installed, properly configured and running. If stateless DHCPv6 support is
turned on, then additional network configuration parameters such as DNS and NTP

you will need to load the ip6_gre module and the ip6_tunnel module for IP6IP6

The following example configures two network interfaces: eth0 is brought up at

whenever the network hardware is detected, and is configured with static IPv4
and IPv6 addresses.

option. (This option is also used by the system boot scripts, so interfaces
marked "auto" are brought up at boot time.)
Line 71, length 87
This can either be during boot if the interface is already present, or at a
later time,
Line 73, length 100
Please note that this does not have anything to do with detecting a network
cable being plugged in.)
Line 82, length 86
Lines beginning with "no-scripts" are used to identify interfaces for which
scripts in

It takes one or more arguments in the form of "CUR=NEW", where CUR is the name
of an existing interface, and NEW is the new name.
Line 89, length 85
This becomes very powerful when combined with pattern matching for the CUR
interface.
Line 93, length 113
So if an interface is started with the name "foo", and it has to be renamed to
"bar" and brought up at boot time,
Line 102, length 99
However, if the interface is not renamed yet, it is possible to use both "ifup
foo" and "ifup bar".
Line 104, length 92
This is mainly useful when ifup is called automatically whenever an interface
is hotplugged.
Line 108, length 85
and may require that the interface that is to be renamed has not been brought
up yet.
Line 195, length 112
A list of packages providing additional options is mentioned in the section
"OPTIONS PROVIDED BY OTHER PACKAGE".
Line 228, length 111
These patterns can currently appear in lines beginning with "auto", "allow-",
"rename" and on the command line.

If no VARIABLE is given, this pattern will match interface names against the
given VALUE.
Line 244, length 143
is run, patterns are replaces by all real interfaces that are currently known
to the operating system kernel and whose names match the pattern.
Line 259, length 92
However, it is possible to combine a pattern with a mapping to a logical
interface, like so:
Line 266, length 99
Valid variable names are "mac", in which case value is matched against the
interface's MAC address.
Line 268, length 82
in which case the value is matched against the contents of the corresponding
file.
Line 270, length 248
The OPTIONS field currently only supports a number. If given, only the n-th
interface that has a matching value will actually be used, where n is the
number given, starting at 1. So /eth*/1 will match the first interface whose
name starts with eth.
Line 272, length 103
On GNU/Hurd, interface names start with /dev/, and this obviously clashes with
the format for patterns.
Line 273, length 81
To ensure an interface name like /dev/eth0 does not get interpreted as a
pattern,
Line 274, length 99
any pattern that starts with /dev/ is ignored, and instead interpreted as a
literal interface name.
Line 292, length 107
As such, a VLAN interface is normally not automatically brought up when its
parent interface is brought up.
Line 294, length 90
in which case all VLAN interfaces that are in the same allow class as the
parent interface
Line 312, length 127
when "ifup --allow hotplug eth0" is called (either manually or because udev
triggers this when a network device is hotplugged),
Line 313, length 83
the interface eth0 and the VLAN interface eth0.1 are brought up, but eth0.2 is
not.
Line 315, length 85
Keep in mind that pattern matching will only match interfaces the kernel knows
about,
Line 316, length 113
so it is not possible to specify "auto /eth0.*" and have all VLAN interfaces
for eth0 be brought up at boot time.
Line 317, length 112
Another way to ensure that a VLAN interface is brought up automatically when
the parent interface is brought up,
Line 329, length 103
since VLAN interfaces are automatically brought down whenever their parent
interfaces are brought down.

Ifupdown uses per-interface locking to ensure that concurrent ifup and ifdown
calls to the same interface are run in serial.
Line 481, length 179
It is therefore important that any hook scripts and \fIpre-up\fR, \fIup\fR,
\fIdown\fR and \fIpost-down\fR commands are written with the possibility of

Any program (person), that produces man pages, should check the output
for defects by using (both groff and nroff)
[gn]roff -mandoc -t -ww -b -z -K utf8 <man page>
The same goes for man pages that are used as an input.
For a style guide use
mandoc -T lint
-.-
Any "autogenerator" should check its products with the above mentioned
'groff', 'mandoc', and additionally with 'nroff ...'.
It should also check its input files for too long (> 80) lines.
This is just a simple quality control measure.
The "autogenerator" may have to be corrected to get a better man page,
the source file may, and any additional file may.
Common defects:
Not removing trailing spaces (in in- and output).
The reason for these trailing spaces should be found and eliminated.
Not beginning each input sentence on a new line.
Line length should thus be reduced.
The script "reportbug" uses 'quoted-printable' encoding when a line is
longer than 1024 characters in an 'ascii' file.
See man-pages(7), item "semantic newline".
-.-
The difference between the formatted output of the original and patched file
can be seen with:
nroff -mandoc <file1> > <out1>
nroff -mandoc <file2> > <out2>
diff -d -u <out1> <out2>
and for groff, using
\"printf '%s\n%s\n' '.kern 0' '.ss 12 0' | groff -mandoc -Z - \"
instead of 'nroff -mandoc'
Add the option '-t', if the file contains a table.
Read the output from 'diff -d -u ...' with 'less -R' or similar.
-.-.
If 'man' (man-db) is used to check the manual for warnings,
the following must be set:
The option \"-warnings=w\"
The environmental variable:
export MAN_KEEP_STDERR=yes (or any non-empty value)
or
(produce only warnings):
export MANROFFOPT=\"-ww -b -z\"
export MAN_KEEP_STDERR=yes (or any non-empty value)
