Andrei made a suggestion.
I think I have tried all the suggestions. The filesystem seems implacable. Everything is there and, as far as I can tell in a ro root filesystem, all seems to be working great. Sooo close. And yet soooo far.
Yes, you just posted now about what Andrei suggested.

You are just demonstrating one of my reasons for not using btrfs :-)
I have never had an issue before. I am sure that my rollback when I mistakenly thought that a zypper dup had mysteriously restarted the system and things looked very wrong are the cause of all this. I was hasty.
Of course, rollback is a wonderful feature. I have known of many people, even novices, using it and saving the day. But if you are stuck, that's big trouble. Me, I know I don't understand btrfs. I know I can not repair its problems by myself. So, I don't use it, not for root. (I use it on external media I use for backup, because it is the only filesystem in Linux that I know of that has transparent compression r/w. And I add an encryption via LUKS.) -- Cheers / Saludos, Carlos E. R. (from 15.5 x86_64 at Telcontar)
