I'm not sure I follow you. If perl is present, documentation is
generated. If perl is not present, documentation is not generated.
Where is the non-reproducibility in this?
RSS doesn't clear out the sysroots if it goes back and executes previous
tasks as part of a rebuild. As such, if perl gets added by a later task,
then bitbake goes back and re-executes the task (I don't remember
exactly which one... do_configure maybe?), perl may be present when it
wasn't before.
This is generally true of all RSS dependencies, and until it gets
resolved the best we can say for reproducible builds is that two builds
from stratch without sstate can be binary identical. It will have to be
resolved eventually, but my current plan is to do the reproducible build
test as two clean builds for now so if there is a lot of push back we
can drop it.
