Hi,

Part of the solution is to create more of them in hurd-boot.scm.

But there’s a second problem: we need to build glibc’s ‘pt_chown’ setuid
program (with ‘--enable-pt_chown’) so that ‘grantpt’ can change the
owner of /dev/ttyp*.

At least that’s how it’s done on Debian GNU/Hurd, but I’m surprised
/hurd/term (for pty-slave) doesn’t just return the right UID on
‘io_stat’.

Ludo’.
