  Target Milestone: ---

Hello,

The check-uniq-files script is returning lots of false positive when successive
builds are launched.

Those detected in the target directory seems to be coming from automatic
stripping that is done in the final step in the target directory:
STRIP_FIND_CMD = find $(TARGET_DIR)
ifneq (,$(call qstrip,$(BR2_STRIP_EXCLUDE_DIRS)))
STRIP_FIND_CMD += \( $(call finddirclauses,$(TARGET_DIR),$(call
qstrip,$(BR2_STRIP_EXCLUDE_DIRS))) \) -prune -o
endif
STRIP_FIND_CMD += -type f \( -perm /111 -o -name '*.so*' \)

When run this commmand modify the modification date of the stripped files, so
on next build, the check-uniq-files script will detect all modified files as
being touched by all packages e.g.:

Warning: target file "./usr/lib/libdevmapper-event-lvm2thin.so" is touched by
more than one package: [u'lvm2', u'popt', u'util-linux', u'cryptsetup',
u'expat', u'dbus', u'e2fsprogs', u'kmod', u'eudev', u'libpng', u'freetype',
u'libopenssl', u'ffmpeg', u'giflib', u'icu', u'libffi', u'pcre', u'libglib2',
u'harfbuzz', u'hdparm', u'ifupdown-scripts', u'initscripts', u'iperf', u'iw',
u'jpeg-turbo', u'jpeg', u'json-glib', u'libcap', u'openssl', u'libcurl',
u'libevent', u'libexif', u'libnspr', u'sqlite', u'libnss', u'liburiparser',
u'libxml2', u'monit', u'openssh', u'udev', u'pciutils', u'strace', u'sysvinit',
u'wireless-regdb', u'wpa_supplicant', u'netgem_bluez5_utils', u'brcm-patchram',
u'netgem-azure-c-shared-utility', u'netgem-azure-uamqp-c',
u'netgem-azure-umqtt-c', u'netgem-azure-iot-sdk-c', u'netgem_boot-bin',
u'netgem_boot', u'netgem_erpc', u'cobalt', u'netgem-bootloader',
u'netgem_nexus_standby', u'netgem_secure_dma_code',
u'realtek_8822BE_BT_driver', u'busybox']

Maybe the -p strip option could be used to avoid this issue ?

Regards.
