My effort at cross install messes up my system. I cannot start a
new terminal or chimera (can start firefox)

    $ chromium

produced these errors:
    

  ERROR:bus.cc(407)] Failed to connect to the bus: Could not parse 
    server address: Unknown address type (examples of valid types are 
    "tcp" and on UNIX "unix")

  ERROR:platform_shared_memory_region_posix.cc(214)] Creating shared 
    memory in /dev/shm/.org.chromium.Chromium.Cqgh9Y failed:

    Trace/breakpoint trap

    $ xterm
    xterm: Error 32, errno 19: No such device
    Reason: get_pty: not enough ptys

But this appears to be normal:

    $ ls -la /dev | grep pty*
    crw-rw-rw-   1 root   tty         5,   2 Oct 18 06:27 ptmx
    crw-------   1 root   root      248,   0 Oct 16 12:35 ptp0
    drwxr-xr-x   2 root   root            40 Oct 16 12:35 pts

Sudo command not functional:

    $ sudo ls
    sudo: unable to allocate pty: No such device

In the machine is a second SSD and I'd like to install to it. However,
the intstaller says it will use the /boot/efi on the old disk. I was
worried that this would make the OS unbootable.
