Smart Only Allows one Kernel to be Installed by Default

[Stephen Morris]

Hi,
      I have been encountering an issue for sometime with Smart 1.4.1 
whereby it will allow, by default, 1 kernel at a time to be installed on 
the grounds that multiple kernel versions cannot co-exist with each 
other. I don't understand why this is the case in Fedora (this occurs in 
all versions from Fedora 18 to Fedora 20) when the same version under 
Mandriva allowed multiple kernel versions by default.
      I can get smart to allow multiple kernels by issuing the 
multi-version flag parameter, but why is this necessary when it is not 
required to allow multiple versions of the kmod.nvidia proprietary packages?
      Having told smart to allow multiple versions of the kernel to be 
installed how do I specify how many versions I want maintained, like can 
be done with the native Fedora package manager?

regards,
Steve
