Hi,

I have to use X for my application (vdr), but X (and dependencies) take
a lot of space, which I want to reduce. Most of it can be found under
/usr/share:

(build) hive mediamachine # du --max-depth=1 -h devroot/usr/share/
132K devroot/usr/share/eselect
24K devroot/usr/share/busybox
8.0K devroot/usr/share/xsessions
12K devroot/usr/share/my_layout
356K devroot/usr/share/ntp
4.0K devroot/usr/share/man
8.0K devroot/usr/share/hwdata
20K devroot/usr/share/et
24K devroot/usr/share/baselayout
28K devroot/usr/share/aclocal
12K devroot/usr/share/ss
16K devroot/usr/share/xorg
4.0K devroot/usr/share/info
4.0K devroot/usr/share/doc
752K devroot/usr/share/fluxbox
12M devroot/usr/share/fonts
1.6M devroot/usr/share/misc
5.4M devroot/usr/share/X11
20M devroot/usr/share/
(build) hive mediamachine # du --max-depth=1 -h devroot/usr/share/X11/
12K devroot/usr/share/X11/app-defaults
3.0M devroot/usr/share/X11/xkb
2.3M devroot/usr/share/X11/locale
5.4M devroot/usr/share/X11/

The big apples are /usr/share/fonts, /usr/share/X11/xkb, and
/usr/share/X11/locale. These dirs contain this:

(build) hive mediamachine # ls devroot/usr/share/fonts/
100dpi 75dpi Type1 cyrillic encodings misc ttf-bitstream-vera
(build) hive mediamachine # ls devroot/usr/share/X11/xkb/
compat geometry keycodes.dir rules symbols
types.dir
compat.dir geometry.dir keymap semantics symbols.dir xkbcomp
compiled keycodes keymap.dir semantics.dir types
(build) hive mediamachine # ls devroot/usr/share/X11/locale/

Now I'm wondering, if I really need all this stuff. At the moment I plan
to run an English system, perhaps adding German, both unicode. I do not
need fancy X fonts for vdr. Do you have any suggestions, what I can
delete and what I should keep?

Regards,
Marc

The nice trick is to run you application(s) under
strace -e file -o trace.log -f cmd..
for some time and see what is really used. Prepare the list of files from the
log and copy them to the target image. Additional research is needed in case
files are opened via relative path.

Works for me. Not very Gentoo-ish though.
