[syslinux] Will syslinux UEFI boot the RHEL7.0 kernel (3.10.0-123.el7.x86_64) ?

Dropped other recipients, don't need a flame war.

What's wrong with putting your opinion in your signature? Let's take a look shall we.

"In general, an opinion is a judgment, viewpoint, or statement about matters commonly considered to be subjective, i.e. based on that which is less than absolutely certain, and is the result of emotion or interpretation of facts." Wikipedia

When we issue an opinion, we nearly force someone else to consider that opinion and it's relevancy towards anything they are doing, especially the first time it is issued. Quite often embedded within the opinion are 'some' of the facts that the issuer drew upon to create the opinion. The receiver may choose to evaluate the opinion based just upon those facts, or they may wish to gather more facts on their own before rendering their judgment on the issuers opinion. Ultimately, however, the receiver must decide whether or not they mostly agree with the opinion. If they do, then everything else communicated by the issuer has more weight with regards to knowledge or situations the receiver is less qualified to evaluate.

Now here is where things get dicey, if they do 'not' agree with the opinion, then the issuer loses status with the receiver. Anything and everything communicated by the issuer becomes subject to a much higher level of scrutiny. So much so, that the receiver may choose to disregard everything communicated just for the expediency of not having to investigate it. Things only get worse from here, because if the opinion is re-issued, the receiver quite often takes it as an insult to their intelligence, and insulting someone is not the way to get things done.

I couldn't even imagine the damage to the reputation of a project that allowed key support personnel to constantly insult would be participants and users. Bashing people over the head with an opinion is very very offensive, and this is exactly what happens when you put an opinion in a signature.

A better way to effect global change might be to approach the IOS.

What wrong with bottom and in-line posting? You always have to hunt for the new words, which is sometimes like finding a needle in a haystack.

Did you try doing just a simple approach of eliminating the menu and
making your LABEL the default?  If you use the following just before
your LABEL and nothing more, it'd probably be your best baseline.

DEFAULT oel70_x86_64
PROMPT 1
TIMEOUT 600

A: Because it messes up the order in which people normally read text,
especially the archives of mailing lists.
Q: Why is Top-posting such a bad thing?
