[ptxdist] UBIFS generation question

[ptxdist] UBIFS generation question

Hi,

I currently add the git commit to my BSP by adding this to a custom overlay
rule.

echo $(shell git rev-parse --verify HEAD) > $(ROOTDIR)/etc/revision

That works fine for creating the file in the platform/root directory.  When
I started to use the UBI image I noticed that file was missing from my root
filesystem.  I see that the ubi.make script does a targetinstall to
platform/images/working_dir and then generates the UBI image from there.
 Which obviously does not have my revision.  How can I fix/modify my line
above so it makes it into both the root directory and the UBI image.

I'm on ptxdist-2011.07.0

Thanks in advance,
Jeff

I personally use `git describe --tags` for this, but that's more a
question of taste.

What about creating the file in projectroot/etc/revision, putting a
placeholder e.g. @REVISION@ in it and using something like this in your
rule:

  @$(call install_alternative, somepackage, 0, 0, 0644, \
    /etc/revision)
  @$(call install_replace, somepackage, /etc/revision, \
    @REVISION@, $(shell git rev-pares --verify HEAD) )

Like this the file gets in the package file and should be installed in
the UBI image. We have a similar approach working in our BSP.
