I'm afraid we probably won't want an option like this.

The question is why in the existing SYSTEM_RSYNC we don't preserve
permissions? I can imagine because sometimes they can be wrong in the
original overlay, for example with version control systems that put all
files read-only.

Yann, Arnout: do you remember why SYSTEM_RSYNC has --chmod=u=rwX,go=rX ?

José: have you considered using a permission table to fixup the
permissions ?

Best regards,

Thomas
