This is a bug in the rootfs rule. You have:
PTXCONF_ROOTFS_MEDIA1="something"
PTXCONF_ROOTFS_MEDIA2="sd"
PTXCONF_ROOTFS_MEDIA3=""
And PTXCONF_ROOTFS_MEDIA4 and later are not set at all. However, the
actual check looks like this:
ifneq ($(PTXCONF_ROOTFS_MEDIA4),"")
@$(call install_copy, rootfs, 0, 0, 0777,
/media/$(PTXCONF_ROOTFS_MEDIA4))
endif
So $(PTXCONF_ROOTFS_MEDIA4) is an empty string and not '""', so this
results in:
@$(call install_copy, rootfs, 0, 0, 0777, /media/)
So /media/ is first implicitly created with '0755' by /media/sd and then
explicitly with '0777' by the rule above. This results in the conflict you
get. I've queued a patch that changes the condition for media subdirs to:
ifneq ($(call remove_quotes,$(PTXCONF_ROOTFS_MEDIA4)),)
This should hit master soon. You can either copy the rootfs.make to your
BSP and make the same change, or you could set all remaining
PTXCONF_ROOTFS_MEDIA* to 'sd' as well. This way none of them hit the bug
and creating the same directory multiple times is not a problem.
