SOURCE BUG Duration: 6s

Subject

- add BB_APPLET_RUNLEVEL used by emdebian via /etc/init.d/rc. Note that we leave the buggy CONFIG_* namespace now, so please fix any applet you thouch.

SOURCE BUG

This commit was genuinely broken at the time (not related to our build system): scripts/config/mkconfigs.c (2005-08-01 - 2006-10-05 arasi) uretilen bbconfigopts.h icine .config satirlarini kacissiz, ham newline'larla gömüyordu - gecerli C degildi, busybox'un kendi bb_mkdep araci bile parse edemiyordu (7d219aab7 ile duzeltildi, mkconfigs shell scripte cevrildi)

→ Bu hatanin tam hikayesini ve duzeltme diffini gor
