Do you need usbwait=5 after a remaster of ISO

[tinypoodle]

Huh?   
non sequitur...

...and it's "waitusb="

[ghosts]

I don't think you really need it until you're booting from a usb? iirc that one is for usbs that are rather slow and won't be recognized by the computer when it boots up. At least that's what I remember reading (?)

[gerald_clark]

It actually has nothing to do with booting, as it is only recognized by the init code after boot is complete.
It is needed any time you have your tce directory on a device that takes several seconds to reinitialize after a software reset.
That includes USB and many CFtoIDE adapters.
Without this option, the scan for the tce directory will miss the slow devices.

[Scooby]

So if you have a remastered ISO with extensions onboard in tce/optional dir
there is no need for waitusb

Correct assumption?

[tinypoodle]

Unless the device is slow in being recognized, e.g. cd connected through USB bus.

On a sidenote: tce/optional should not reside on a read-only filesystem, please search wiki for "remastering".
