You understand wrong.  /dev/pts was constructed because the semantics
of BSD pty's is broken (there are issues with permissions.)

You should fix your applications.

Absolutely not.  BSD and Unix98 ptys have different semantics, and
absolutely, positively, must be kept separate -- or you have a
security hole in your machine.

Fix your old applications.

/dev/pts question

2001-04-18 Thread elko

hello,

as I understand, /dev/pts was created
to make an end to the overload in /dev/
and let the kernel put the entries in /dev/pts
when they are used/needed/installed.

but still, when I enable /dev/pts, I have to
keep the /dev/ for backward compatibility
with already installed applications that rely on them.

would it be possible/sane to make like a
/dev/* (some sort of a /dev/B-compatible) besides
/dev/pts, where the kernel `translates' the
/dev/ request to /dev/* and then
`translate' that to the correct /dev/pts entry ??

at least, something like that...
