No, I disagree.
First of all, what are you trying to do? Upgrade your kernel or compile closed-source drivers against your current kernel?
If you're trying to upgrade your kernel, then you can go either way. If you're trying to compile something against your current kernel, then I would strongly suggest that the kernel-source provided by the distro is a better way to go, because then you know it's exactly
the source of your actual running kernel, with the same compiler, the same tweaks/settings optimized for slack (insofar as Slackware optimizes anything for you ahead of time
), etc, and all you have to do is install it and you can proceed with compiling the drivers, without having to recompile the kernel and reboot to it, etc.
I'd be interested to know what "security issues" the 2.6.3 kernel-source in slackware-current would have that the 2.6.3 kernel-source on kernel-org would not
. They're the same kernel, just that the one is slackpacked, and has a slack-optimized config, afaik.
