The use case that currently does work is:

while true; do make randconfig; done

 If there is something wrong with depends/select chains, you'll get the
occasional error like

warning: (BR2_PACKAGE_FOO) selects BR2_PACKAGE_BAR which has unmet direct
dependencies (!BR2_STATIC_LIBS && BR2_PACKAGE_HAS_UDEV)


 My invalid fix of randconfig would make that use case less relevant, because
the invalid chain may depend on some choice value.


 I guess it must have been Yann who explained it to me, not you :-)

 Arnout
