Hmm, spoke too soon. I guess this is indeed a bug in rpm. It's true
that for
Requires: (G if H)
'G' and '!H' is put in the index, so that 'rpm -q --whatrequires G' will
return 'richdep' and 'rpm -q --whatrequires !H' will also return richdep.
But
Requires: (G if H else I)
is the same as
Requires: (G if H)
Requires: (I or H)
so *both* 'H' and '!H' need to be in the index. I.e., if we remove H we
need to make sure that I is installed and if we install H we need
to make sure that G is installed.
Cheers,
Michael.
