Ben:-
Nah, you're fine; don't worry about it. You're
not being ungrateful; only regular community members could possibly be aware of what Mick's had to cope with this last couple of years. You couldn't be expected to know.
With regard to older Puppies working better when they run as LiveCD then save back to the disc, yes; that's always been one of Pup's strengths. Many distros will run as a LiveUSB, and be able to employ 'persistence' (I think that's what it's called), but to the best of my knowldege, Puppy alone is pretty much unique in being able to save back to the very same disc it was booted from...
Admittedly, most of us run frugals from either USB or HDD/SSD these days, but a few of the 'old guard' still prefer their Live 'multisession' CDs/DVDs..! Takes all sorts, don't it?
-------------------
As to your quote, above, er, yeah; things have gone a wee bit south recently. Gyrog (aka 'gyro' on the old Murga Forums) has been completely re-writing the initrd scripts over this last 18 months or so. Even he admits it's not yet running as smoothly as he'd hoped; which begs the question, why interfere with what BK himself put together several years ago?
BK's still around, but he's got his own projects now. Stepped-down 5 or 6 years ago, and handed the reins over to Mick, who is now the official 'steward' of the Puppy community. It's largely self-maintaining (basically a 'do-ocracy'; if someone feels like doing something, they do it!), but it can get a bit over-excitable at times.
Thr re-write has been prompted by the way certain new classes of hardware have had to be catered-for in Puppy's unique way of doing things. We'll get there eventually....
Mike.
