Boot embedded linux faster


Hi there,

I'm working on an embedded linux and I want to speed up the boot process.
Using http://elinux.org/Boot_Time I already added some improvements but I need help to know what rc scipts I can suppress from boot process or run later or in parallel.

Here are the rc scripts being run:
- mountvirtfs
- bootlogd
- udev
- checkroot.sh
- checkfs.sh
- mountall.sh
- ifupdown => will be run later
- hostname.sh => will be run later
- networking => will be run later
- portmap
- mountnfs.sh => Will be run later (not used in production release)
- bootmisc.sh => ???
- urandom => will be run later
- udevtrigger

Does someone know if I'm right ?

Thanks

I don't use rc scripts at all. I run only required commands from may script. Here are results: http://www.makelinux.com/emb/fastboot/

I found that Micro-core Linux has a nice, fast, easy to understand, and easy to customize model for it's init scripts. Actually, it is pretty much just a single script, which I think is good for embedded systems. I'm currently using microcore as the basis for an embedded x86 package.
