The solution would be to do as sudo does: cache the password for a given period of time.

Which is already what happens during the stages that shouldnt be run as root.

Well, my cats don't have an official certification that they're European race. Doesn't mean they aren't ;)
You know, looks like a duck, talks like one, etc. 

The fact you can't sell it as Unix is a distinction that IMHO matters only to marketeers and lawyers...

The thing with HDDs is that you can predict failure only when they start failing. There's of course a MTBF estimate, but for each individual pair of HDDs you could just as well see the new one fail almost immediately and the old one last years more as the opposite (given identical use).
SDDs have the advantage of being much more resistant to mechanical wear and abuse, but then again it wasn't the HDD that failed in my Powerbook which accompanied me in 3 motorcycle accidents and thousands of kms.

No, and I got a lemon at that too. 

>There's also an SDXC port there.  You can get a micro SDXC card and one of the many flush-insert adaptors

Is that port really different from the SD card port I have in my 2011 MBP? I've never dared investing in a SDXC card but the more affordable ones of a reasonable size tend to be disappointingly sluggish in certain operations. Otherwise they'd probably make a good choice for putting a filesystem journal (or ZFS ZIL).
