Now[*] I get the reverse of the problem.  The mode is set correctly (and
is changeable) for all devices *except* fd*, mem, port, sd*, and scd*.
For those, the mode is fixed at 666.  There is no error code returned, and
chmod simply does nothing.  This, BTW, is happening in a regular directory
(/ddev), with the virtual /dev still in place...

There also were some glitches with the /ddev devices (notably clipboard,
which I've exercised quite often), but nothing I could pin down, and all
with 1.5.12 (unfortunately, I couldn't switch to a snapshot for my
everyday use -- maybe on next reboot).

Another glitch that *is* reproducible for me is that bash cannot
tab-complete any top-level directory or file (unless PWD=/, in which case
"ls ^I^I" works, but "ls ./^I^I" doesn't).  I can provide more details if
needed.
