Thank you for taking the time to report this bug and helping to make
Ubuntu better.

It seems to me that /proc/self/exe being broken in overlayfs is a bug in
overlayfs, not in perl or logwatch. But I am interested to hear what the
kernel team decide on this.

Presumably this either needs to be fixed in overlayfs, or in every
package that uses /proc/self/exe. It would make sense to make an Ubuntu-
wide decision on the appropriate course of action here.

Launchpad's bug tracking allows for a single issue to be tracked across
multiple packages. I think this is an appropriate issue to track this
way, since it will stop discussion and appropriate decisions on the same
issue being scattered across many bugs.

So I'm marking this bug as a dupe of bug 1030519, renaming bug 1030519
appropriately, and will add a logwatch task to bug 1030519 to track it
there. Please continue discussion in bug 1030519.

I also think that this issue should probably be marked Invalid in both
perl and logwatch, since it is reasonable to expect /proc/self/exe to
work. But I would like to hear the kernel team's opinion on this first.
I'm not marking this as a dupe of the kernel bug 1007089 pending
feedback from the kernel team.

Mike, have you tried contacting the kernel team on this? The ubuntu-
devel or kernel-team lists would probably be appropriate here. Also,
this mailing list post seems relevant: https://lists.ubuntu.com/archives
