Would it be enough for the "your old screen binary is
/tmp/screen-yhpoe8r/screen" notice to also say "if your /tmp is mounted
noexec, you might need to copy it elsewhere to run it"? Or you could just
assume that any sysadmin who has deliberately enabled noexec (not the default,
after all) is able to realise (and deal with) the consequences :-)
