I was remembering why your file name approach made me nervous. in Windows
NT, you could open files that you did not see via readdir. This is kind of
crazy making, after a while.
So in your server, you're either going to see all those files on a readdir,
which will confuse users and scripts; or, if
I've planned to pass xattrs through the ,ctl files, but haven't written the
code yet - I've only recently installed the xattr package on RPi debian and
read the man pages. It looks reasonably straightforward. It's been bottom of
the list, as I don't see a lot of things using them.
I've written

This is cool :)
Can you pass xattrs through the ,ctl file ?
If you can find the time to write it up in thee pages, that would be a
nice WiP for iwp9 ! The deadline has just been extended !

It's nice to see I'm not the only one doing something of the kind. I
went with something that seems simpler to me, but
I have a complicated relationship with 9P2000.L. On the one hand it's been a
useful way to build file systems for Linux, and I've gotten some mileage out of
that. On the other hand, I'm not crazy about having a different protocol to 9P
