Ok, now I remember that we discussed this once, but never fixed it.
The problem is:
in texlive-base-bin.preinst the following happens (more or less):
# try to move tetex version
check_move /etc/texmf/xdvi.cfg /etc/texmf/xdvi/xdvi.cfg $version
-> . file /etc/texmf/xdvi.cfg is not readable
. we upgrade from a previous version
. thus we generate /etc/texmf/xdvi/xdvi.cfg.preinst-deleted
# now the texlive version of the file
check_move /etc/texmf/texlive/xdvi.cfg /etc/texmf/xdvi/xdvi.cfg $version
->
scenario 1: file /etc/texmf/texlive/xdvi.cfg is readable but unchanged
. remove unchanged config file /etc/texmf/texlive/xdvi.cfg
scenario 2: file /etc/texmf/texlive/xdvi.cfg is changed
. mv /etc/texmf/texlive/xdvi.cfg /etc/texmf/xdvi/xdvi.cfg.preinst-copy
then we come to postinst ...
-f /etc/texmf/xdvi/xdvi.cfg.preinst-deleted
-> Preserving removal of $cfgfile
-f /etc/texmf/xdvi/xdvi.cfg.preinst-copy
scenario 1: NO -> do nothing, file disappeared !!!
scenario 2: YES -> mv ... , file still present.
So if you changed it in texlive, it is present
If you didn't change it, it is gone.
The solution is problematic because we cannot check whether we upgrade
from a tetex version or a texlive version (both could be installed,
removed (but not purged), reinstalled etc etc).
So I suggest the following code instead of the one currently present
in common-function.preinst:
# for xdvi.cfg we first want to move tetex files, and later
# texlives
/etc/texmf/xdvi/xdvi.cfg)
# here we have to care for the tetex version
# we cannot use check_move because if it is not present
# because tetex was never installed then a -preinst-deleted
# will be created. So we do the same as check_move but a bit
# different:
#
orig="/etc/texmf/xdvi.cfg"
new="/etc/texmf/xdvi/xdvi.cfg"
if [ -r "$orig" ] ; then
mdorig=$(dpkg_md5sum "$orig")
if [ $(md5sum "$orig" | cut -f 1 -d ' ') = "$mdorig" ] ; then
rm "$orig"
else
mkdir -p $(dirname "$new")
mv "$orig" "$new".preinst-copy
fi
else
if [ -n "$version" ]; then
# we are upgrading from texlive, so this does mean
# that the tetex version was never installed or purged
# don't create the preinst-delete, just do nothing
:
fi
fi
# now set the conf_oldpath to the texlive version
conf_oldpath="/etc/texmf/texlive/xdvi.cfg"
;;
esac
check_move $conf_oldpath $cfgfile $version
