I tested this. Took an dd image of my pbx and restored it onto a spare 16GB Sandisk MicroSD card I had lying around, then started.
Well, 3.5 hours later it was still pounding away doing all sorts of horrors. Wait I/O was off the scale...suspicious. Generating locales was taking an hour for each one.
Eventually canned it, and booted up my old microSD.
When I looked at the card I used for the upgrade, I was shocked to find it was a class 2!!
(Well, actually given what happened, it now made sense)
I have no idea where I got that card from - must have come as a boobie-prize with some toilet paper or something. Didn't know I owned one of those.
Anyway, let that be a warning - double-check what class your card is
before you start.
Code:
jackass() {
if [ Doofus = true ]; then
skip Card-class check
experience pain
acknowledge stupidity
start over from scratch
fi
}
I'll try again another day with a "right, proper" card, not this piece of junk.
