And if you are a old fart who has bad memory like me, put it in the |
| 31 |
make.conf as a default. That way it takes no effort to keep a clean |
| 32 |
world file but does take effort to add something to the world file. I |
| 33 |
have to rebuild a individual package a lot more than I need to install a |
| 34 |
new package. I learned long ago, don't trust my memory to do things by |
| 35 |
default. Heck, I have to think about it to remember to add the -N to |
| 36 |
regular updates still. I been doing that for years. If it wouldn't |
| 37 |
screw up other things, I'd set it as a default but that causes another |
| 38 |
set of issues. Go ahead, tell me to do updates in script. ROFL |
