ArchOne is Arch Linux (32bit, i686 version).
The packages, commands, print to boot, installation, etc... are the same of Arch Linux.
The only differences are the selection of the software and configurations in /etc, that are in use on my aspire one.
Every 30 mount, a partition is checked to find errors. There are situations where you would like this doesn't happen.
Eg: you have to project a slide and you have to do it fast, or you have little time and you just check the email.
For all those special occasions, you can boot Linux without checkdisk. Use at your own risk: this boot is fine if rarely selected: you should select standard boot every day.
