Subject: [schroot] Add support for overlay mounts.

Date: Sat, 19 Dec 2015 14:34:25 +0200

[Message part 1 (text/plain, inline)]

Source: schroot
Version: 1.7.2-2
Severity: wishlist
Tags: patch

Hi,

First of all, thanks a lot for maintaining schroot and the rest of
the automatic build infrastructure!

A couple of months ago, aufs stopped working in the 4.x kernel for
a while.  It was fixed afterwards, but in the meantime I threw
together this simple thing that adds support for overlay mounts
(not quite the same as the existing overlayfs support).
One of the drawbacks is that overlay mounts need an additional directory
as scratch space, so there's a whole new directory/property/method
added to various classes and configuration objects, and there's
a little pain in transitioning from an aufs chroot to an overlay one,
since this directory needs to be created first.

Just let me know if you're interested in this, and I can see what
it will take to port the patch to schroot-1.7.3, and also document
the new additions properly.  If not, and/or if aufs works in a stable
manner now and it can be used again, well, yeah, feel free to close
this bug report, I'm just putting this out there as a proof of concept
or something :)

G'luck,
Peter

I don't understand everything, during last Debconf I uploaded 1.6.10-2
with this change:

  * Add support for overlay filesystem in Linux 4.0. Closes: #785633
    Thanks to Antonio Teirceiro and Felipe Sateler for the patch.

It's probably missing in the experimental version but you're speaking
of "porting" the patch to 1.7.3... do you mean porting your own patch
from 1.7.2 to 1.7.3 (is that released upstream?). Or porting Antonio's
patch to 1.7.x?

Cheers,

Version: 0.2.1-13
Distribution: unstable
Urgency: medium
Maintainer: Peter Pentchev <roam@ringlet.net>
Changed-By: Peter Pentchev <roam@ringlet.net>
Closes: 808387
Description: 
 wmanager   - window-manager selection tool used at X startup
Changes:
 wmanager (0.2.1-13) unstable; urgency=medium
 .
   * Bump the debhelper compatibility level to 9:
     - use debhelper's invocation of dpkg-buildflags, drop the versioned
       build dependency on dpkg-dev
     - use dpkg-buildflags's hardening flags, drop the build dependency
       on hardening-includes
   * Add the 05-strdup patch, replacing two unguarded uses of strcpy()
     with strdup().  Arguably the strcpy() uses were safe enough, but
     there's no harm in using strdup() and removing a Lintian warning.
   * Bump Standards-Version to 3.9.6:
     - drop the DM-Upload-Allowed field
   * Split the DEP-3 author information into several Author fields for
     the patches with multiple authors.
   * Update the copyright file to the 1.0 format and bump the years of
     my Debian packaging copyright notice.
   * Rewrite wmanagerrc-update in pure Perl, replace the perl5 and chase
     dependencies with perl:Depends.  Incidentally, Closes: #808387
   * Drop the version from the 'menu' suggestion, satisfied in oldstable.
   * Add the debian/upstream/metadata file.
   * Add Multi-Arch: foreign to the binary package.
   * Drop the source compression options; dpkg-dev's defaults are good enough.
   * Add --parallel to the debhelper invocation.
   * Switch the Vcs-Git and Vcs-Browser URLs to my GitLab repository.
   * Do not use the full path to update-menus.
