Here are a few
- You don't need POSIX multi-open semantics, hangup and the like
- Seek makes sense on some kinds of fixed attributes
- TTY has a relatively large memory overhead per device
- Sysfs is what everything else uses
- Sysfs has some rather complete lifetime management you'll need to
redo by hand
- You don't need idiotic games with numbering spaces
Abusing tty for this is ridiculous. In some ways putting much of it in
kernel is ridiculous too as you can do it with a FUSE fs or simply
export the info guest-guest using SNMP.
