有非常多的 PaperLinux Project 文件..
包括了 UML simulator、Initial RAM-disk、Linux-7k,
Paper 包括了 Booting LinuxLinux Network Traffic Control等等還有一堆的好東西~ 🙂

一個跟 Booting Linux 相關的資訊~ fast boot 🙂

In the Bootup Time working group in the CE Linux forum, we've broken
it down into 4 major areas:
- firmware
- kernel init
- user init (daemons, scripts)
- application init
For firmware init, we are interested in kernel XIP (and general firmware
time-bloat reductions - maybe LinuxBIOS?)
For kernel init, we are interested in 2 and 3. Also, we are interested
general probing reductions (eg. idex=noprobe is broken in 2.4 - haven't
checked 2.6 yet.)
For user init, we have done some work with modifications to busybox to
make RC scripts execute faster.
For user init and application init, we have looked at application XIP,
and are potentially interested in pre-linking.
