Subject: [gentoo-embedded] How are pttys created in embedded gentoo?

1 I now have an sshd running on my embedded gentoo setup, but when I try
2 to connect I get the following message on my embedded gentoo server:
3
4 openpty: no such file or directory
5
6 Indeed, there are no pty in /dev.

8 Doing a bit of research, I learned that there is a new scheme to create
9 pseudo ttys as needed:
10
11 ............... a virtual file system which can be mounted on
12 /dev/pts with "mount -t devpts". This, together with the pseudo
13 terminal master multiplexer /dev/ptmx, is used for pseudo terminal
14 support as described in The Open Group's Unix98 standard: in order
15 to acquire a pseudo terminal, a process opens /dev/ptmx; the number
16 of the pseudo terminal is then made available to the process and the
17 pseudo terminal slave can be accessed as /dev/pts/<number>. What was
18 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
19
20 The GNU C library glibc 2.1 contains the requisite support for this
21 mode of operation; you also need client programs that use the Unix98
22 API.
23
24 Does the gentoo-embedded libc support this? If not, then we need to make
25 all those pseudo ttys manually.
