and in /srv/fai/config/store/setup-storage you need to have line 77 as follows
  unshift @INC, "/var/lib/fai/config/store/lib";

Have you considered this instead?

use lib ""/var/lib/fai/config/store/lib";


Which will then allow you to have an entire FAI:: namespace down that path? Unless you wrap the 'unshift' into a BEGIN{} block, it happens at run-time (which is too late), not compile time like 'use lib'. BEGIN blocks are ugly and tough to debug, where as 'use lib' falls into the natural order/perly of doing things.

It might even be better to put the config-store libs in a central place that all of FAI can find them, possibly in /usr/lib/fai, which gets rolled into the NFSROOT. You can then do things like:

 use FindBin;
 use lib dirname(abs_path($FindBin::RealScript)) . "/../lib";
 use lib "$FindBin/../lib";
 use FAI::Config::Store;
 my $bin = $FindBin::Bin;

if you needed to. This allows for an FAI/ subdir some place relative where the script running lives, and provides a location for an entire FAI:: namespace.

Additionally, in setup-storage, there is the following:

 require "init.pm";
 require "volumes.pm";
 require "parser.pm";
 require "sizes.pm";
 require "commands.pm";
 require "fstab.pm";
 require "exec.pm";

Which seems to be an attempt to get around the fact that the 'unshift @INC' is a runtime operator. If the unshift were converted to a "use lib", all the requires could be converted to 'use' statements as well, and all this would happen at compile time where it's supposed to.

Just some thoughts.

preserve option

could anybody give me the right trasformation of this configuration to the new format

disk_config hda
primary  -              preserve1
primary  -              preserve2
primary  /             100-         rw,errors=remount-ro ; boot -j ext3 
logical  swap          128         sw                   

especially i don't understand the preserves

thanks a lot


disk sda / hda

Is there a reason why all the examples use

disk_config hda

or

disk_config sda

instead of the more generic (and probably more generally applicable)

disk_config disk1

(specific partitions can be addressed as 'disk1.3')
