Hello,

Questions to those who have a Pi under their hands and are knowledgeable in Linux.

How long does it take to boot the system? (is SD Card fast as can an SSD be?)

Can the Linux distrib, be personalized as to load very fast, hide the linux startup screen for a Logo and stop user from using anything else than a chosen app?

TIA.

I"ve not timed it, but using the current Debian image my Pi boots in under a minute to the login prompt.

and if you want to limit to a particular program you can provide an image that auto runs that with changed splash screens - no problems

Thanks all.

I'll come back for more tech details, when I can get my hands on a Pi.

It take my pi a bit over a minute to boot, but I'm using a class 2 SD card that isn't 100% compatible.  It works and once it boot there are no i/o errors or anything, but on boot it goes through a bunch of start up jitters that unnaturally increases the standard boot time.

Yes, I produced an image that boots to play a video in about 6-8 seconds.

If you need to limit it to one app for security reasons, then be careful that you still do things like change the root and user passwords (defend against ctrl+alt+f1), ensure the various stuffs that allow the user to kill X are disabled, hide the Pi in a locked box, and so on.

To customize it, the simplest thing to do is to put an image (e.g: the Debian or Arch one) on your card, and make the modifications as you would on any Linux machine. If you want, you can then image customized version.
