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.
30 # We'd like to detect whether filesystem we are on has coarse mtimes,
31 # but can't do it yet, bbox ls hasn't got --full-time.
