Concatenate initramfs on Windows

<< < (2/4) > >>

sodface:
There's another best practice that goes "never say never"!

The only archive I created on Windows was the extra initramfs archive which only contained extensions.  The mydata.gz was created previously on piCore.

In this case it seems to work ok.  Here's how the additions look from piCore after boot:

DrRob:
I am wondering if it might be possible to create a tool that takes all the packages that have been added into piCore and generate a custom initramfs with everything already in it so that extensions don't need to be loaded separately at boot time, and if so would that speed up the boot process?  What do you think?

curaga:
Sure, I think there's a script for that posted here somewhere.

Try this script.
It merges all extensions you want into a single tcz, that should reduce your boot time without touching initramfs.

Thanks, I'll take a look at that.
