I've seen the threads on 90% hangs re: 6.0.1, but...

I went through everything I could find, did a fresh install on a Nexus 5, it did hang at 90% (didn't see the thread on using a different recovery until too late, used twrrp). I left for awhile, then re-booted. It loaded fine, with working wifi...

Since it did hang at 90, does that mean it failed to finish installing something? I drop into term and everything seems to be there and working. I would just hate a surprise to pop up when I needed something.

Haven't plugged in external wifi yet, but will check that in a bit.

I've also seen a few threads about not running the regular apt update/upgrade, should I steer clear of that?

Thanks.

If you check the running messages on your fone it would say something like checking for chroot in su or something. If it takes longer than expected reboot system. So I think its ok.
