[Libguestfs] xfs protofiles for libguestfs

Hi all, I hope I am in the right place, I found this email by following the link in the project README. We are collecting use cases for xfs dev projects, one of which would be enhancing xfs protofiles, which is a type of script that facilitates filesystem generation. I am not very familiar with libguestfs, but a coworker suggested that this might be of interest to your project. More specifically, the task would be to add attributes to the files generated by the protofile script. Does this sound like something that might be of use to libguestfs? I did take a quick glance through the libguestfs code, and didnt notice any current usage of xfs protofiles, but I thought it was worth asking if protofiles might become of interest if we did add this feature. Thanks! Allison
