thank you all for your answers, I'll try to be complete here, but brief 1st, Im not having any troubles - normal ops are fine, sudo dnf update works, etc.
only oddity is with dual boot - 1st few attempts to boot win10 failed after installing 24-beta (not an upgrade from f23). But recent attempts now seem to work, theyre just a little thrashy (iirc, the bios seems to boot 2x - 2 toshiba splash screens) but it gets there. This is my 1st EFI bios machine, so I dont have anything to compare it to.
[jimc@buffy ~]$ more /etc/fedora-release Fedora release 24 (Twenty Four)
[jimc@buffy ~]$ more /etc/system-release*: ::::::::::::: /etc/system-release :::::::::::::: Fedora release 24 (Twenty Four) :::::::::::::: /etc/system-release-cpe :::::::::::::: cpe:/o:fedoraproject:fedora:24
So thos are good, but I dont know whether any of these said "beta" anywhere before final release
[jimc@buffy ~]$ rpm -qil fedora-release Name : fedora-release Version : 24 Release : 2 Architecture: noarch Install Date: Mon 27 Jun 2016 02:10:28 PM MDT
my /etc/os-release matches Darios but again I dont know if it said beta earlier.
[jimc@buffy etc]$ dnf repoquery --duplicated Last metadata expiration check: 0:36:45 ago on Tue Jun 28 10:02:03 2016. so that looks clean
$ cat /var/lib/dnf/system-upgrade.json {"upgrade_status": null, "download_status": null}
which seems kind-of empty, and counter to what Rick Stevens expected in it, but again I dont know how it looked before..
to satisfy curiosity, I ran:
[jimc@buffy dnf]$ pwd /var/lib/dnf [jimc@buffy dnf]$ sudo strings history/history-2016-05-04.sqlite | less
saw lots of 'fc24', but no 'beta's other than (mostly) taglib packages.
at this point, things are fine, so Im not gonna sweat the off-chance that I might still be at "Beta" - all the packages upgraded to final.
In a few weeks I'll be back to those fc23 boxes, will do those upgrades, and if that suggests anything pertinent here (longshot) I'll follow up here.
thanks again y'all
