Subject: [gentoo-vdr] Size reduction...

Hi,

I'm trying to build a minimal gentoo vdr system using uclibc and
busybox, which boots completely in ram using initramfs of kernel. The
reason behind this is, that I want a system, which boots as fast as
possible. To realize this I want to reduce the size of the rootfs as
small as possible. Now I come to my questions:

1.) I have to use X, since my motherboard (via epia 8000 sp) is only
properly (more or less) supported with X drivers. Fonts for X are taking
up to 12 MB! Does vdr use or need any fonts of X? If not, I could remove
them.

2.) Today I run a test, which packages would be installed on a clean
system for vdr:

(build) hive / # mm_merge_bins -pt vdr

These are the packages that would be merged, in reverse order:

As far as I can see perl is pulled in by Test-Harness and PodParser. Can
you tell me what this stuff is needed for? For me perl is a big
dependency, which I would like to get rid of.


Well, that's it for now. Thanks for any help in advance!
Marc
