-where 'ns_exec -cm /bin/bash' calls clone() with CLONE_NEWNS flag and execs
-/bin/bash in the child process.  A pty created by the sshd is not visible in
-the original mount of /dev/pts.
 
 Total count of pty pairs in all instances is limited by sysctls:
 kernel.pty.max = 4096		- global limit
-kernel.pty.reserve = 1024	- reserve for initial instance
+kernel.pty.reserve = 1024	- reserved for filesystems mounted from the initial mount namespace
 kernel.pty.nr			- current count of ptys
 
 Per-instance limit could be set by adding mount option "max=<count>".
 This feature was added in kernel 3.4 together with sysctl kernel.pty.reserve.
 In kernels older than 3.4 sysctl kernel.pty.max works as per-instance limit.
-
-User-space changes
-------------------
-
-In multi-instance mode (i.e '-o newinstance' mount option is specified at least
-once), following user-space issues should be noted.
-
-1. If -o newinstance mount option is never used, /dev/pts/ptmx can be ignored
-   and no change is needed to system-startup scripts.
-
-2. To effectively use multi-instance mode (i.e -o newinstance is specified)
-   administrators or startup scripts should "redirect" open of /dev/ptmx to
-   /dev/pts/ptmx using either a bind mount or symlink.
-
-	$ mount -t devpts -o newinstance devpts /dev/pts
-
-   followed by either
-
-	$ rm /dev/ptmx
-	$ ln -s pts/ptmx /dev/ptmx
-	$ chmod 666 /dev/pts/ptmx
-   or
-	$ mount -o bind /dev/pts/ptmx /dev/ptmx
-
-3. The '/dev/ptmx -> pts/ptmx' symlink is the preferred method since it
-   enables better error-reporting and treats both single-instance and
-   multi-instance mounts similarly.
-
-   But this method requires that system-startup scripts set the mode of
-   /dev/pts/ptmx correctly (default mode is 0000). The scripts can set the
-   mode by, either
-
-   	- adding ptmxmode mount option to devpts entry in /etc/fstab, or
-	- using 'chmod 0666 /dev/pts/ptmx'
-
-4. If multi-instance mode mount is needed for containers, but the system
-   startup scripts have not yet been updated, container-startup scripts
-   should bind mount /dev/ptmx to /dev/pts/ptmx to avoid breaking single-
-   instance mounts.
-
-   Or, in general, container-startup scripts should use:
-
-	mount -t devpts -o newinstance -o ptmxmode=0666 devpts /dev/pts
-	if [ ! -L /dev/ptmx ]; then
-		mount -o bind /dev/pts/ptmx /dev/ptmx
-	fi
-
-   When all devpts mounts are multi-instance, /dev/ptmx can permanently be
-   a symlink to pts/ptmx and the bind mount can be ignored.
-
-5. A multi-instance mount that is not accompanied by the /dev/ptmx to
-   /dev/pts/ptmx redirection would result in an unusable/unreachable pty.
-
-	mount -t devpts -o newinstance lxcpts /dev/pts
-
-   immediately followed by:
-
-	open("/dev/ptmx")
-
-    would create a pty, say /dev/pts/7, in the initial kernel mount.
-    But /dev/pts/7 would be invisible in the new mount.
-
-6. The permissions for /dev/pts/ptmx node should be specified when mounting
-   /dev/pts, using the '-o ptmxmode=%o' mount option (default is 0000).
-
-	mount -t devpts -o newinstance -o ptmxmode=0644 devpts /dev/pts
-
-   The permissions can be later be changed as usual with 'chmod'.
-
-	chmod 666 /dev/pts/ptmx
-
-7. A mount of devpts without the 'newinstance' option results in binding to
-   initial kernel mount.  This behavior while preserving legacy semantics,
-   does not provide strict isolation in a container environment. i.e by
-   mounting devpts without the 'newinstance' option, a container could
-   get visibility into the 'host' or root container's devpts.
-   
-   To workaround this and have strict isolation, all mounts of devpts,
-   including the mount in the root container, should use the newinstance
-   option.
