I currently use sysinstall with the install.cfg configuration file for an
automatic installation.
I need to make sysinstall formating only a small FreeBSD partition of the
disk and not the whole disk, or the free space.
I already have a function that give me the size of the partition that I
need to format.
I would just like to choose the offset and the size for create_chunk().
The file that interest me is disks.c, in /usr/src/release/sysinstall, at
the end, there is the all and free options...
I would like to create another option, added to "all" and "free",
says "custom" where I could specify the offset and the size.
The problem is that I can't do this by taking some parts of "free" option
code, because it doesn't seem to work ("unable to find X slice" or
something like that, "X" is set in create_chunk.c, see later)
Can anybody give me the structure of a whole disk accorded to sysinstall?
with chunk structures, ...
Or if someone know how to implement this, I would be glad to heard about
it...
(I think that I could take the code of "free" option a little bit
modified)
Others useful files are /usr/src/lib/libdisk/ create_chunk.c and chunk.c
Thanks!
