Re: [Ltib] How to force a package build if its PRECONFIG changed?

[Stuart Hughes]

Hi Peter,

This is not straightforward as you need to compute which preconfig is
actually going to get used (as in busybox.spec and similarly for the
kernel).  The names are in in $pcf->{PKG_KERNEL_PRECONFIG} and
$pcf->{PKG_BUSYBOX_PRECONFIG}, but the paths need to be computed.  So
assuming you can do this, you'd need code around 770, where the rpm
rebuild logic occurs along the lines of:

my $cf_upd = @rpms && (-M compute_preconfig_path($key) < -M $rpms[0])
.....
$r .= "config file has been updated", " if $cf_upd;

Sorry I don't have more time to look into this further, but hopefully
this is of some help.

Regards, Stuart
