SOURCE BUG Duration: 14s

Subject

I'm about to introduce tests that need to run as root (like mount.tests), meaning we want to run them in a chroot environment. To help with this, I worked out a utility function that makes it really easy to set up a chroot environment.

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)
