Hi all, I already mentioned an Acer One boots very fast from flash, like 5-10s to X server with window manager loaded. I remembered that I can do a TAR.BZ2 of the whole root of the SSD and put it online somewhere, if anyone cares to have a look to see what they have done at Linpus to speed up the boot of this particular Fedora flavour.
We could supposedly download it from here: http://www.linpus.com/products_1.php# But, at least for me, it's not quite working. I volunteer for that effort but would like to have some help from Wade, since I've mostly used Gentoo since I became a penguin, and I don't known much else. Gentoo uses a different init system from most distros, so I never did do much init system hacking out of Gentoo. When I did do it(OpenSUSE and Ubuntu, mostly writing init scripts and toying with the boot process), it was something I didn't want to do again, I love Gentoo's baselayout too much - it's simple to work with and supports parallel init script startup for at least three years. Take a look at: http://www.youtube.com/watch?v=Mg_HBgwRZS4 to get an idea of how fast it is. It boots the X and window manager and then starts loading network and ACPI stuff in parallel, it still takes a while for everything to be up but it's generally quite fast, especially if you just want to access local stuff.
