Mount the proper virtual (kernel) file systems on the newly-created directories:
mount -vt devpts -o gid=5,mode=620 none /dev/pts mount -vt tmpfs none /dev/shm
The mount commands executed above may result in the following warning message:
can't open /etc/fstab: No such file or directory.
This file—/etc/fstab—has
not been created yet (unless using the boot method), but is also
not required for the file systems to be properly mounted. The
warning can be safely ignored.
