I must have come to a page similar, but to not recall previously seeing
all the choices showing on that page linked above. I saw one choice only
for the netinstall at the time I downloaded the iso. ISTR it was about a
week after buster was announced.
Would it have made a difference when asking about a realtime kernel for
it?
If the armhf netinstall boots via grub I'd consider that enough of a
plus, as I might do a rebuild as all those srcs are on a separate drive
I could disconnect while the netinstall was running. 64 gig u-sd cards I
have already.
Thank you.
Cheers, Gene Heskett
