I have been playing with the thought of a hybrid. You load all runtimes |
8 |
(binary executables) into RAM and run them from RAM. But you mount |
9 |
a /var partition on disk (maybe an encrypted partition?). You have your |
10 |
software on readonly cdrom, your configuration on floppy/usb and your |
11 |
data (/var) on disk, mounted as noexec. |

There are floppy images on the iso image for booting from both cdrom and |
18 |
usb. usb.flp has drivers needed to load the system from usb. |

I want to save space but dont expect to reboot so often. We are solving |
25 |
different problems. :) |

Do you have the firmware (and drivers) in gentoo portage? what ebuilds? |

busybox should be enough. |
