If distributions offer more than one way to install and manage software, then this would be absolutely beneficial to ensure that terrible things don't happen (like the package manager removing sqlite because it was upgraded by something other than it). Especially in Mageia, where we are preparing to move to DNF, and we are planning to use the Hif backend for PackageKit and will offer DNF as a fully supported option with Mageia 6, it would be extremely useful if the user-installed and dependency tracking could be moved to the rpmdb. Generally speaking, I'm not certain why this *isn't* in the rpmdb already, as most distributions have historically offered more than one way to install software (Fedora with yum, apt, and smart; openSUSE with zypper and yum; Mageia with urpmi and apt; PCLinuxOS with apt and smart; and so on). If not in the rpmdb, maybe another database managed by rpm could keep track of this information? -- 真実はいつも一つ！/ Always, there's only one truth! _______________________________________________ Rpm-ecosystem mailing list Rpm-ecosystem@lists.rpm.org http://lists.rpm.org/mailman/listinfo/rpm-ecosystem
