pretty incredible that i didn't get a chance to actually do any googling
before i had more info than i knew what to do with! for example:

i'm way far away from understanding awk & sed. so {something}, in this case
would be {permissions are set properly at boot}? but what's the

i got that one out of the library a few months back, and yes, it was helpful.
i'll google for the how-to's & console tips. thanks for the recommendations!
