Re: [Ltib] mtd-utils: dependencies and versions

[Stuart Hughes]

Hi Joseph,

Unfortunately it would be desirable to put requires/buildrequires into
the spec files, but in practise this causes more problems than it
solves, hence dependencies are handled in the config system.

BTW: if you want to have an alternate spec file to select a different
version of a package for your platform, you can use the pkg_map facility
(see the FAQ)

Regards, Stuart
