I've read the hardware page on the wiki to find out what I will miss out on:
- Memory: 128 MB. I can build a swap file/partition in order to overcome this.
- Storage: 128 MB. What is the use of this storage? Since I will be installing Linux on external drive, does this internal storage contain only the bootloader? In that case 128 MB for bootloader is sufficient.
- No JTAG: Since I've no knowledge of hardware, what is JTAG's use? After reading installation instructions, it doesn't look like I need JTAG in order to install Arch Linux ARM install.
- Not a Sheeva Processor: Are there packages that I will not be able to install/use because the Processor is not Marvell Sheeva?
Thanks for answering all my newbie-type questions.
