Subject: [Resolvconf-devel] Bug#887176: resolvconf should depend on
	e2fsprogs explicitly
Message-ID: <20180114191043.GA19215@alf.mars>

Package: resolvconf
Version: 1.79
User: helmutg at debian.org
Usertags: nonessentiale2fsprogs

Dear maintainer,

We want to make removing e2fsprogs from installations possible. For standard
installations this is not useful, but embedded applications and chroots benefit
from such an option.  For getting there all packages that use e2fsprogs must be
identified and gain a dependency on it as e2fsprogs currently is essential.

resolvconf was identified as potentially needing such a dependency,
because it mentions tool names from e2fsprogs in the following files:

/usr/share/resolvconf/dump-debug-info contains lsattr. According to file it is a POSIX shell script, ASCII text executable
DEBIAN/postinst contains chattr and lsattr. According to file it is a POSIX shell script, ASCII text executable

Please investigate whether these cases are actually uses of a tool from
e2fsprogs. Care has been taken to shrink the number of candidates as much as
possible, but a few false positives will remain. After doing so, do one of the
following:

 * Add e2fsprogs to Depends.
 * Add e2fsprogs to Recommends.
 * Close this bug explaining why e2fsprogs is not used by this package.

Once e2fsprogs drops the "Essential: yes" flag, this bug will be upgraded to RC
severity. Please note that lintian will warn about such a dependency before
lintian 2.5.56.

Thanks for your help

Helmut

This one uses lsattr, but guards the execution with checking if it
exists first, so no strict dependency needed for this. Basing my
assumption on the file name a Suggests would likely be more warranted
than a Recommends.

The postinst maintainerscript does indeed use both chattr and lsattr.
Both of them are guarded with the debconf variable
resolvconf/linkify-resolvconf having to be TRUE, which is the default.
A dependency is thus currently needed here!

An alternative approach if there's a reason to consider avoiding adding
a strict dependency would be to refactor the debian/config to check
for chattr/lsattr existance and if they're not available force the
debconf variable resolvconf/linkify-resolvconf to false (likely together
with a debconf prompt stating that). I'm not sure if the extra
complexity is worth it and it would be great if maintainer(s) could
comment on this.

My conclusion is that a e2fsprogs dependency is likely the best
solution.

Andreas Henriksson

Hi there,

Is there any special reason not to add e2fsprogs as a dependency?

Cheers,
Thomas
