installation without installer

[Sleep_Walker]

Hi,

I'm owner of Sharp PC-Z1 Netwalker with Ubuntu 9.04 preload. Netwalker unfortunatelly doesn't have support in vanilla, so I have to use 2.6.28 sources provided by Sharp.

I'd like to upgrade to 9.10 (and later probably 10.04). Unfortunatelly I can't boot anything else but internal flash or SD card. Furthermore I have no SquashFS 4.0 support in kernel. So I'd like to perform installation steps without booting Ubuntu usual way.

I extracted squashfs filesystem from provided image and unpacked all to card, added old kernel and booted. It worked but the system seems to be unconfigured in many ways.

I don't know Ubuntu much so I'd like to ask how to perform installation without running installer. I'd like to do it as clean way as possible and share the result with other Netwalker users.

Thanks

Best regards,
