That's true.  I've never got around to correcting my siggy in my gnus

This is standard practice; you don't usually need to indicate that
you've snipped at all (except maybe by leaving a blank line in between
the quoted bits where the snip was), much less the number of snipped
lines.

Not quite; as you've written it, your name _is_ the signature.

The '-- ' is not technically part of the signature; it's the signature
_delimiter_, i.e., the thing which sits between the signature and the
rest of the message. As such, it has to be the very first line of the
signature block. (In practice it will usually be included in the
signature file, but that's an implementation detail.)

Does this latter actually work?

I would expect it to use the same hold mechanism as 'apt-mark hold' or
'echo "packagename hold" | dpkg --set-selections', and in my experience
holding a package as not installed does not work; it doesn't even get
recorded in the package-selection state, and certainly doesn't get
respected later when another package Depends or Recommends that package.

If that's been changed, or if there's a mechanism which avoids it and
does work, I'd be very interested.

The standard for signature delimiters is a line consisting of '-- ', as
the first line of the signature block. Software which knows what it's
doing will see this line and treat whatever comes after it specially -
for example, leave it out when quoting a message for reply.

If what he(?) really wants to do is treat his name as part of the post
and any (un-snipped? bottom-quoted?) text below that as special, then
his current signature delimiter is _almost_ correct - the "almost" being
because he has a space before the '--' as well as after, so the
delimiter won't be recognized by most software.

If he's aiming for a normal signature delimiter, however, he does indeed
have it slightly wrong.

I agree.  I tested "hold" on an uninstalled package with aptitude,
nothing happened.

So your option is to use /etc/apt/preferences as described in
apt_preferences(5) where new glob(7) syntax for package is described.

This is not tested but it should be like:

   Package: /^texlive-.*-doc$/
   Pin: release a=*
   Pin-Priority: 10

This glob feature is available from apt (0.8.14)  Apr 2011.

This worked.  (Priority 10 was not small enough.)

Re: removing TexLive Docs packages

The aptitude command line I suggested removed such documentation packages as

texlive-fonts-extra-doc
texlive-fonts-recommended-doc
texlive-latex-extra-doc

apart from the science, pstricks, and pictures doc packages. The language
docs had to be handled specially because of the transition.

This is not a way to remove a package. It is a way to delete files which
were installed by a package (and won't work correctly even for that in
this case, since this package's files not only use multiple file
extensions but are spread throughout a fairly sizable directory tree),
but is not recommended in pretty much any case.

It will also not prevent the package's files from getting reinstalled
later on, so it doesn't really address the question which was asked.


The correct approach would be to remove the appropriate texlive-lang-*
package (e.g., texlive-lang-english) which contains the documentation,
using e.g. 'apt-get remove texlive-lang-english', and then blacklist the
package from being installed using the method suggested by Osamu Aoki.

(There is no 'texlive-doc' package in current testing as far as I can
see, and the 'texlive-doc-en' package appears to be a transitional dummy
package; it appears to be superseded by texlive-lang-english, so I infer
that that is the documentation package in question. Note that because of
this naming difference, the removal command suggested by Udyant Wig
probably wouldn't get the job done, at least not by itself.)
