I'm coming from Ubuntu/Debian/MSDOS/Fedora (but mainly Ubuntu) , I saw Haiku featured in LinuxFormat magazine, and was intrigued. I wasn't around to see BeOS, but from what the article said, and what I see in your slideshow, I like the idea and the 'look'. Questions, though:
1) What command-line does it use, and where do I learn about it?
2) Which bootloader does it use, or does it use its own?
3) I have been developing packages for Ubuntu for a while (with mixed success), but I understand Haiku has a different approach. Where can I find a brief explanation of how Haiku manages packages/updates, and how to become a Haiku developer?
4) Does it even have a package manager?
In case you hadn't guessed, I haven't booted Haiku yet (slow Internet). Sorry for newbiness, I genuinely haven't touched anything that's not Linux/Microsoft based.
