If ten seconds seem interminable, you need to get a life!

Doesn't work on most of my systems. This always does:
Let me see.
I have two real computers beside my desk with RHEL-clone or Fedora. One
normally runs Windows and has half-a-dozen or more virtual machines with
Linux (mostly Debian, but still with grub). Across the room my sever
runes RHEL4-clone. in the house my internet gateway runs another
RHEL4-clone. My wife's system runs RHEL-clone, I have two laptops with
Fedora and one with opensuse, all with grub. Over there in the corner
are a couple of test systems, those too have grub. As has my wife's
Yesterday, I got tired of installing broken Fedora (gosh, I hope F12
isn't the base for the next RHEL!!), and installed Ark linux instead. It
happens it was on a DVD attached to a magazine.
I'm for ever updating grub menus!
Actually, there's a good reason I go for even longer timeouts sometimes.
My work system has a one-hour timeout. The reason?
Sometimes, we have a power failure. It makes good sense for desktops to
boot after servers, so the servers are good and ready to serve out IP
Sometimes, not often, there is a small succession of power failures. The
one-hour delay ensures that the desktop gives the power supply ample
time to settle down. If, as is often the case, I'm not there, it usually
doesn't matter if it's down for a while, most times I don't notice.
OTOH if I really am present, pressing a key or two to boot appropriately
really is trivial. Even if ten seconds does seem for ever!
In contrast, with short delays on some systems the screen hasn't even
settled down from the graphics card being reinitialised and the grub
display's not even visible.
When it is visible, it is still too easy for one's attention to wander
while POST does its thing.
Especially on Fedora (and opensuse and debian testing), automatically
booting the latest kernel is a recipe for disaster. It will happen that
you will install a kernel that will not boot. It happened to lots of
people with FC3, it happened (fortunately after I made an enormous fuss
it got fixed before Golden Day) with Fedora 8 (or thereabouts) betas.
Kernel 2.6.25 it was. 2.6.24 was fine.
