[Syndri]

Yes that is how big the core is for ubuntu 9.04 Jaunty
I am building my own ubuntu around it with this site
It is an amazing thing if u dont want all the unimportant stuff u will never use
Just get what you will need, meaning it will run faster cause no bloat

That's pretty cool. I usually start off with the Ubuntu Minimal (https://help.ubuntu.com/community/Installation/MinimalCD) ISO, that lets me install the only packages I need from command line. The 30 MB bootable seems really nice, I'll give it a shot. Thanks.
