The current "rd.cmdline=ask" prompt is very easy to miss during the boot
process, as it's just a single line of text that often gets buried among
other kernel messages.
It improves the user experience by:
- Adding a high-visibility 80-column ASCII banner to clearly signal that
input is required.
- Refining the text to clarify that both kernel and install program parameters
are accepted.
- Implementing a temporary 'trap' for SIGINT (Ctrl+c). Since the 'd' key is
physically close to 'c' on most layouts, it's easy to accidentally kill
the script when trying to send EOF (Ctrl+d).
- Using shorter, consistent sleep intervals for a smoother rendering of the
banner.
Old prompt:
Enter additional kernel command line parameter (end with ctrl-d or .)
New prompt:
========================================================================
(o< >o)
//\ INPUT REQUIRED !!! /\\
V_/_ _\_V
========================================================================
Enter additional kernel command line, or install program, parameters.
End with a period "." or Ctrl+d in a new line:
