/etc/postinstall/fontconfig_dtd.sh could check whether
/etc/postinstall/libxml2.sh exists. If so, it could run it and then
add '.done' so it isn't run again.
While this seems to maybe solve this particular problem, I really don't
think that it is a good idea to have postinstall scripts run other
postinstall scripts and then deactivate them behind the back of
setup.exe. Please let's not go there,
I agree. That was a bad idea.
if there is a general need to
coordinate among postinstall scripts let's try to solve that within
setup (the stratified postinstall concept does allow for something like
that, it's just not yet fully specified or implemented).
I don't think a general need has been demonstrated. This is the first
case I can recall seeing.
I do think that this case should be fixed, one way or another, in
/etc/postinstall/fontconfig_dtd.sh. That script assumes, on the basis
of [ -x /usr/bin/xmlcatalog ], that the catalog /etc/xml/catalog has
already been created.
