I don't blindly answer those questions even tho it can be time consuming |
36 |
at times. I tend to look at a new feature as something I don't need, |
37 |
since I'm not adding hardware. I still look to see if it is something |
38 |
new that could be useful. The new features are usually marked as new so |
39 |
they're easy to see. What gets me, it asks for something that I've |
40 |
already done before and it has the option I chose before already |
41 |
selected but asks me anyway. That's kinda weird. |
42 |
|
43 |
When I was going through oldconfig, I noticed that when I answered yes |
44 |
to a new thing, files system option that I could possibly need one day, |
45 |
that a whole bunch of related new stuff followed behind it. It makes |
46 |
logical sense but it does open a can of worms for sure. |

I wish there was a better way to update kernels but thing is, I can't |
49 |
figure out a better way to do it either. I suspect if there was a |
50 |
better way, someone would have figured it out by now anyway. ;-) |

Now to reboot this thing, eventually. lol |
