Package: initramfs-tools
Version: 0.120
Severity: normal
Tags: patch

Dear Maintainer,

First of all, thank you very much for maintaining
Debain's initramfs-tools package.

I love to see generous and civic minded people.

When I was upgrading the kernel with

    $ aptitude install linux-image-686-pae

I happened to notice that it failed with

    The following partially installed packages will be configured:
      linux-image-4.0.0-1-686-pae linux-image-686-pae 
    No packages will be installed, upgraded, or removed.
    0 packages upgraded, 0 newly installed, 0 to remove and 2486 not upgraded.
    Need to get 0 B of archives. After unpacking 0 B will be used.

    dpkg: dependency problems prevent configuration of linux-image-686-pae:

      Package linux-image-4.0.0-1-686-pae is not configured yet.

So the kernel wasn't upgraded.

I believe the problem is that the /var/tmp/
directory did not exist.

Since /var/tmp is specified in Debian's Filesystem
Hierarchy Standard[1], it seems to me that it was
somehow deleted.

However, I have no clue as to who, what, when,
where or how.

/var/tmp was also reported to be missing in bug
report #696771[2], so it's not just me.

Humble suggestion: 

Since /var/tmp is specified in our FHS, is
required to update the kernel, and is being
deleted, patch /usr/sbin/mkinitramfs to check if
it exists, and if it doesn't, create it.

Here's a patch.

I hope it makes sense, and is in an acceptable
format.

It is not the responsibility of initramfs-tools to create /var/tmp.
/var/tmp is part of base-files, which is an essential package.

We can't generally cope with things being mysteriously deleted from
other packages that we depend on (or are essential), and I see no reason
to work around this specific deletion.
