[ptxdist] Adding package independent files in the root filesystem

[ptxdist] Adding package independent files in the root filesystem

[Mircea Ciocan]

Hello everybody,

I have some configuration files that are package independent, but board 
depended, is there a solution to add them in bulk to the root filesystem.

It seem that configs/platform-XXX/projectroot only holds configuration 
files that overrides the default ALREADY EXISTING files in the root file 
system, all other files seem to be ignored.

Is there some "magic" setting that allows a full projectroot copy and 
overwrite/add the content to the rootfs or is there another way to get a 
similar effect ?


  Many thanks,

  Mircea

Only files that are installed by an enabled package using
install_alternative(_tree) [1][2] are taken from projectroot.

Create a new target package with "ptxdist newpackage target", remove
everything but PACKAGES-$(PTXCONF_YOURPACKAGE), YOURPACKAGE_VERSION,
YOURPACKAGE_LICENSE and the targetinstall stage. In the targetinstall
stage you can use install_alternative_tree [2] to install "the whole
source directory tree with all files" [2].

Care must be taken not to install files with this that are installed by
another package already.

Bastian

Create another package for those files. That's what we did at work in
our BSPs.

I would suggest `ptxdist newpackage file` which seems to be the
template for exactly that usecase. Of course you could go with every
other template and adapt it or create a package from scratch, but the
'file' template gives you a very simple .in rule and a .make rule with
just the targetinstall stage active, you don't need more to just
install some files to the target.
