20# Mtime granularity problem.
21# It was observed that these commands:
22# make allnoconfig; sed -i -e '/CONFIG_TRUE/s/.*/CONFIG_TRUE=y/' .config; make
23# sometimes produce busybox with "true" applet still disabled.
24# This is caused by .config updated by sed having mtime which is still
25# equal to (not bigger than) include/autoconf.h's mtime,
26# and thus 2nd make does not regenerate include/autoconf.h.
27# Waiting for 1 second after non-interactive "make XXXXconfig"
28# prevents this from happening.
