Bug#60461: debian-policy: FHS conformance not explicit
Package: debian-policy
Version: 3.1.1.1
Severity: normal
The current policy document does not make explicit that packages ought
to aim to be "compatible" with FHS, rather than "compliant".
Furthermore, the policy does not make explicit *which version* of FHS
one ought to follow. There is a passing reference to the fact that
a pre-release FHS is included in the policy document, but I believe
this information should be made more explicit. (When people have to
guess at what a policy document means, trouble is likely)
I am appending a diff containing my best shot at clarifying these
issues.
When I brought this issue up on debian-policy, Chris Waters suggested
that I point out the fact that current policy actively prevents packages
from being "FHS compliant" (a higher level of conformance than mere
"compatibility"). I have included a few lines about this in the actual
policy document, because it is important for new developers to
understand some of the rationale for settling on "mere" compatibility.
