Jens,

Thanks for reporting and thanks for the patch. But I'm afraid fixing this is
not that easy. You've correctly added the font to the keepfiles list, but it
won't get installed into the install image root in the firstplace as there seem
to be nothing in the packages list which installs said font.

The packages list still contains old font-package names / aliases:
        fonts-arabic fonts-bengali
        fonts-chinese fonts-gujarati fonts-hindi fonts-indic fonts-ISO8859-2 
        fonts-kannada fonts-korean fonts-malayalam fonts-oriya fonts-punjabi 
        fonts-sinhala fonts-tamil fonts-telugu

Most of these are no longer available in rawhide, for example there is no
fonts-korean in rawhide, so no korean fonts will get installed at all.

It looks like we need to take a good look at which fonts packages we are
currently installing into the install image root, and at which are listed in
the keepfiles list.

I'm CC-ing the fonts-bug-list hoping that one of the font SIG guys can help out
here.

Font SIG guys, when anaconda (the installer) is running it runs in its own
environment. This environment gets build by the upd-instroot script. This
script starts by installing a list of packages into a chroot and then removing
any files not in a list of files to keep, so as to reduce the footprint of the
install image, currently the lists of packages being installed to get the
necessary fonts to get the installer to be able to render text in non western
charactersets is listed above. This list clearly is no longer correct for
rawhide, we could use some help in getting it fixed.

Hans - the packages list can also contain things that are Provided: by other
packages, since this list is just fed into yum.  So for example while there is
no fonts-arabic package, kacst-fonts Provides: fonts-arabic, so the right
package will get pulled in.

Here, nothing is providing fonts-korean anymore so the new font package will
need to get pulled in.  This list certainly does need auditing, but the
situation isn't quite as bad as you're thinking.  I've made this update and
am
putting the bug in modified for that reason.  We can continue to work on
auditing the list and then close this one when complete.

I know, but the fonts-lang provides are going away. So we need to stop using
them.

Counter example:
[hans@localhost devel]$ repoquery -q --whatprovides fonts-chinese
[hans@localhost devel]$

This is on rawhide.

It does see me example above. Which make me think we should add a reverse check
on the keep files list, iow error out when a file in the list is not in the
install-image, does this sound like a plan ?

Ack.

The default install list in the @fonts group is supposed to provide support for
all our locales. Is it for some reason not good enough for you?

Well for one our current script only handles packages, not groups, but we could
fix that, besides that we are trying to keep things as small as possible (this
goes on boot.iso) so it would be good to know if there is anything we could
leave out for the installer case. For example it serves little purpose to ship
fonts for language for which there is no anaconda translation.

So some questions:
1) The fonts-lang aliases are going away, right?
2) Is there a table somewhere with lang -> needed font mappings
3) Are there any fonts in the font group which are there to for example have
   a decent selection of fonts for language foo in openoffice, but which could
   be left out without affecting the ability to display language foo?

fonts-lang packages have not been representative of our language support for
quite a long time. What we had was a mix of font-lang packages and font
packages named another way. During the past releases we've tried to consolidate
font support by first renaming font-lang packages so they follow the same
conventions as other font packages (keeping legacy aliases to their old names)
and then in the future we'll kill those aliases too.

>  2) Is there a table somewhere with lang -> needed font mappings
I've tried to get the L10N teams fill
http://fedoraproject.org/wiki/Localization_fonts_requirements

but it's not been a huge success. I'm afraid only local guys know which font is
best for them.

>  3) Are there any fonts in the font group which are there to for

I think the intention is to have a default font selection in @fonts which is
sufficient to display all our locales, and then have additional fonts for foo
locale defined both in @foo-support comps group and as optional @fonts members.
Of course the package lists are not as complete and accurate as we'd like them
to be and an audit is always welcome.

Thus while the default fonts list in the @fonts group is probably closest to
what you need, it will have two defaults:
— it covers all the scripts we know of, not just the scripts needed by anaconda
locales
— it will have some duplication (for example latin is important enough we
install both liberation and dejavu by default)

However maintaining this list is already a lot of work and I don't see us
maintaining another one just for anaconda. (Of course if comps had some notion
of inheritance we could do stuff like "@fonts group is composed of
@anaconda-fonts + those fonts anaconda does not care about")

I am happy to provide the list of packages (it is basically just default
packages in @fonts as Nicolas says).  I will just update my patch to update the
package list too then for now.

I agree though that it would be much better the @fonts group could just be used
though.

Not sure if any other updates are needed for the filelist: it looks like quite
a lot of stuff (fonts anyway) could be pruned from it.

Using the @Fonts group is probably not doable until we rework the stuff in
scripts/ to be in Python and use yum objects, instead of how we're doing
everything now.  That's not going to happen for F10 at least.  For now we can
take your patch updating the font list, though.  We probably can prune out a
lot of the old crud, but it seems to me there's a fairly high possibility of
breaking something in the process.

Finished updating the font list in anaconda.  This should be taken care of in
the next build, though we still need to look at using the @Fonts group for the
future.
