OK, thanks. Now I've got this straight. I should do something like
dlls/mountmgr.sys/device.c, where I'd have an NT device like
\Device\CdRom0 (or some such), whose FD I'd pass to the server so that
when NTDLL opens the device and gets its FD, it still has the CD-ROM
device for client-side calls. But when I need to call mountmgr, I open
\Device\CdRom0 (or some such) and pass the IOCTL on to mountmgr. Is that
right? Or am I still missing something?
