Dear Paulo,
A: Because it messes up the order in which people normally read text.
Q: Why is it such a bad thing?
A: Top-posting.
Q: What is the most annoying thing on usenet and in e-mail?
And you not only top-post, you also full-quote. And you post HTML, even though this is strictly forbidden on this list.
You are ignoring Netiquette more or less completely, are you aware of this?
I think you should read http://www.netmeister.org/news/learn2quote.html really carefully.

I got a board that uses u-boot to load the system. The u-boot is installed and already working. Now I want to configure u-boot to load another rootfs through nfs. The original bootargs variable has less than 255 characters but with the new configuration the variable will be more than that. I just want to know if it's just a configuration that I have to setup or I have the recompile u-boot...
There is no inherent limit on the length of an environment variable. It can grow as long as you have memory for it.
Best regards,
