+ <heading>A special case in <prgn>update-fmtutil</prgn>:
+ Formats which are based on other formats</heading>
+ <p>
+ The JadeTeX and xmlTeX formats are built on top of LaTeX
+ and therefore require special treatment. This is done
+ automatically for the Debian packages for these formats.
+ However, local administrators who similarly base their
+ custom formats on LaTeX (or any other format) might need
+ to take special care, in particular when dist-upgrading.
+ </p>
+ <p>
+ JadeTeX is based on LaTeX such that during format
+ generation, the LaTeX format dump is preloaded with this
+ line in <file>fmtutil.cnf</file>:
+<example>
+jadetex etex language.dat &latex jadetex.ini
+</example>
+ This is problematic if the package which provides LaTeX
+ (currently <package>texlive-latex-base</package>) is
+ upgraded at the same time as the package which provides
+ the executables
+ (currently <package>texlive-base-bin</package>). In this
+ dpkg run, <package>texlive-base-bin</package> will be
+ configured while <package>texlive-latex-base</package> is
+ unpacked but unconfigured and might have
+ a <file>10texlive-latex-base.cnf.dpkg-new</file> file
+ in <file>/etc/texmf/fmt.d</file>.
+ <package>texlive-base-bin</package> will
+ call <prgn>update-fmtutil</prgn> just before it executes
+ <tt>fmtutil --all</tt>, and because of
+ the <file>dpkg-new</file> file information for LaTeX will
+ not be included. If JadeTeX would still be included, its
+ format generation would consequently fail.
+ </p>
+ <p>
+ <prgn>update-fmtutil</prgn> knows about this problem and
+ will ignore JadeTeX and xmlTeX if LaTeX is not
+ available. It does not know which other (locally
+ defined) formats are also based on LaTeX, though. To
+ prevent failures (and actually a possible fork bomb, see
+ Debian Bug #427562), local administrators should manually
+ disable such formats before upgrading TeX Live packages.
