[Bug 1516543] Re: dpdk-init depends on executables in /usr/bin

[Robie Basak]

14:19 <rbasak> cpaelzer, smb: would it be possible to have a dep8 test
that requires virt isolation, checks that there is exactly one mount,
restarts the service and checks that there is exactly one mount again?

Unless there's a good reason not to, I'd like to see a dep8 test for the
functionality of mounting hugetlbfs without duplicates along with the
fix please, validated by failing before the fix and passing after the
fix. We're packaging this directly and freshly in Ubuntu and DPDK will
be doing into main shortly, so we have the opportunity of keeping the
packaging top quality. If we're adding something for packaging that
isn't upstream and we can test it, we should.

OTOH I accept that trying to make sure it works even if the system
doesn't have /usr mounted is harder to test and may not be practical
given our current tooling, so best effort for that without a specific
dep8 test is fine.

There was some discussion of this at

Title:
  dpdk-init depends on executables in /usr/bin

Status in Ubuntu Cloud Archive:
  New
Status in dpdk package in Ubuntu:
  Fix Committed

Bug description:
  /lib/dpdk/dpdk-init depends on a few executables in /usr/bin to parse
  the current mounts on the host; however the init script only makes use
  of /bin and /sbin so fails to execute correctly, resulting in
  duplicated mount.
