I think this is generally a bad idea. You should have more respect to the intentions of your users. If a user defines a specific bootdelay setting in his environment, this must be respected.
I really hate vendors who believe they know better than me what I want or what is good to me. Please get rid of such stuff.
"bootdelay" is an environment variable that is intentionally user definable. You must never mess with those.
Best regards,
Wolfgang Denk
