I can CD into them endlessly, and both "ls -lR" and "find ." report cycles in
the tree, which surprised me that they had a specific error message for that,
actually. Good enough for me. :)
And I'm not _complaining_ about it. Just fiddling around with fun stuff. If
I get really bored I'll figure a way to split the tree so there are two
completely unconnected mount trees in different processes. (Get a private
namespace that's chrooted into something that somebody else does a umount -l
on from their space. Or without using umount -l, just have two processes
chroot into other mount points which should theoretically garbage collect the
old root if no processes still references it, which presumably means one of
the processes is init...)
Don't mind me, I do this for fun.
