I suppose that when you tell : b1 depends on a1 explictly you would tell
that exist in the b1 spec an Requires : a = 1: in this case the
upgrading will block yes
e.g. rpm -Uvh will tell you
error: Failed dependencies:
a = 1 is needed by (installed) b-1.0-1.noarch
But you can put an Obsoletes: b in a2 spec and b1 will be removed
automatically. e.g
rpm -q b
b-1.0-1
[root@joke ~]# rpm -Uvh /home/machbuild/rpmbuild/RPMS/a-2-1.noarch.rpm
