I've just made a Live USB stick with Ubuntu 11.10 USB creator. I tried it on 2 laptops and the boot time is very long, more than 5 minutes. Is it normal?
If it is, what is the interest of having a portable OS if it take ages to boot?
With a 2GB memory stick, I reduced the persistent memory from 4 to 1GB and the boot time was faster, less than 2 minutes. I tried with an 8GB USB stick again with a persistent memory of 1GB, and the boot time is 4 minutes.
It seems that the boot time is linked with the USB memory stick and persistent memory size.
Is that true? Will the boot time be faster with a "class 8" USB memory stick?
It depends on your usb stick and maybe your usb port is not usb2?
It could take 5 minutes, although in most cases it shouldn't. For it never was faster than a hard-drive boot.
The interest of having portable os is mainly because it is portable... And as opposed to a live cd you can make changes to it that will remain after a reboot. alt+enter during boot, i get a black screen with nothing written, no console, nothing
