Yes, I did know that and wasn't precise - thanks. user_version is
31 for both.

Yes, probably true.

Yeah, it must be, but given that the systems are so similar, I
wonder what the difference is. The one that is broken is an AWS
lightsail instance, and the other is my own physical RAID5 hardware, same
drive, but different partitions, so perhaps that is why it works.
I have gotten it to work this morning by doing a sparse checkout
up to the mount point and then setting the depth on the mount point to
infinity, and I've tested various operations trying to break it, and I
couldn't. I also tried svn:externals, but referring to the direct child
path, and subversion (rightly so) doesn't like that.
Use of excessive, unnecessary, commas, has always been,
one of my, pet peeves.
