SOURCE BUG

This commit was genuinely broken at the time (not related to our build system): sysdeps/linux/Config.in "fileutils/Config.in" dosyasini kaynak gosteriyor ama bu dosya repoda hic var olmadi (2002-12-05 - 2003-02-15 arasi orijinal yazar hatasi, 3238ea167 ile duzeltildi)

→ Bu hatanin tam hikayesini ve duzeltme diffini gor

- help
- Say yes if you are using the ip command instead of route and ifconfig
- in your scripts to bring up the interface.
- This is needed as ip wants the subnet as a bitprefix not an ip value.
