# Mtime granularity problem.
|
|
# It was observed that these commands:
|
|
# make allnoconfig; sed -i -e '/CONFIG_TRUE/s/.*/CONFIG_TRUE=y/' .config; make
|
|
# sometimes produce busybox with "true" applet still disabled.
|
|
# This is caused by .config updated by sed having mtime which is still
|
|
# equal to (not bigger than) include/autoconf.h's mtime,
|
|
# and thus 2nd make does not regenerate include/autoconf.h.
|
|
# Waiting for 1 second after non-interactive "make XXXXconfig"
|
|
# prevents this from happening.
|
|
#
|
|
# We'd like to detect whether filesystem we are on has coarse mtimes,
|
|
# but can't do it yet, bbox ls hasn't got --full-time.
