            Bug ID: 15838
           Summary: dhcp server creates symlinks to /tmp on host
           Product: buildroot
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned@buildroot.uclibc.org
          Reporter: jonas.d.karlsson@gmail.com
                CC: buildroot@uclibc.org
  Target Milestone: ---

In package/dhcp/dhcp.mk this section can be found:

ifeq ($(BR2_PACKAGE_DHCP_SERVER),y)    
define DHCP_INSTALL_CTL_LIBS    
        $(MAKE) -C $(@D)/dhcpctl install-exec DESTDIR=$(TARGET_DIR)    
endef    
define DHCP_INSTALL_SERVER    
        mkdir -p $(TARGET_DIR)/var/lib    
        (cd $(TARGET_DIR)/var/lib; ln -snf /tmp dhcp)    
        $(MAKE) -C $(@D)/server DESTDIR=$(TARGET_DIR) install-sbinPROGRAMS    
        $(INSTALL) -m 0644 -D package/dhcp/dhcpd.conf \    
                $(TARGET_DIR)/etc/dhcp/dhcpd.conf    
endef    
endif

The symlink that is created from /var/lib/dhcp to /tmp seem to cause a symlink
to the host /tmp which creates access privilege problems.

Shouldn't the symlink be to ../../tmp rather than /tmp like the misc symlink
under /var/lib? See below 

cd output/target/var/lib

ls -al
