===============
structure is cool, but it seems like you're being human-centric in your
reference to structure; i actually want to parse the info with a script,
making kenv preferable.
i want the ability to run the script without any privileges; again making
kenv preferable.
so with an unprivileged script, i'm leaning towards kenv to find out what
hardware is running (motherboard & system info, eg "Dell Inc., 0H603H,
PowerEdge 2950" or "Acer, Navarro, Aspire 5100").
other than being formatted more nicely (for humans, anyway) and only
running with root privileges, is there any ~real~ difference between the
information i would get from dmidecode rather than kenv (as it relates to
motherboard & system make & model)? it seems like in either case, i'm just
getting the info from smbios... and that info could be good, bad or ugly
regardless of how it's formatted.
