Re: [Xen-API] How to built XCP from source-1.iso ?

[George Shuklin <george.shuklin@xxxxxxxxx>]

Hi.

Repack is not the 'rebuild'. Repack is simple unpack and pack back, may 
be with changes. We do this too (and we actually replace installer with 
our own to reduce amount input questions).
"Dark magic" I'm talking about is how to get dom0fs.tar.bz2 from clear 
CentOS installation and bunch of source files.
Some of files (afaik) even had no source code. F.e. you can not get 
xs-tools.iso (shipped inside XCP to plug to guest domains) from source 
code, because windows part (paravirtualized drivers) are closed source.
xcp-xapi on ubuntu/debian is much more opensource, you can rebuild them 
completely from scratches, but they are not very stable (xapi part is 
fine, but all interaction between xapi and other services is 'done 
somehow' and under some condition breaks).
