[byers@f12 ~]$ uname -r 2.6.32.11-99.fc12.i686.PAE login SElinux error trying to boot my backup copy of f12. Main f12 on external usb at /media/rootusb7, ext4. Backup f12copy on external usb at /media/rootusb8, ext3. Both use same /boot on internal hdisk, sdb8. I think i got the changes correct, UUID change in fstab, and in grub.conf new stanza. system booted ok, X came up, but login as user gives error msg something close to: " could not connect to session bus: An SELinux policy prevents ..sender from sending this message to this recipient (rejected message had sender "(unset)" interface "org...desktop.DBus"...member..error name...........)" I didn't write it down legibly enough to repeat all of it here. I had to hit the power button and reboot into my main f12. I know zilch about SELinux, took the defaults on install. The man page talks about label...relabel... restorcon, none of which I understand The gui shows enforcing enforcing targeted I suppose I could try to disable selinux on this backup copy. does "selinux=0" on the kernel line suffice? Frowned on, I suppose, but for something mostly not to be used, maybe ok? pointers? advice?
