Severity: normal
Tags: patch

Dear Maintainer,

   * What led up to the situation?
While configuring the live-config.timezone parameter (on kernel boot parameter
or by config.conf file) to any value, hence 'Europe/Paris', the only result is
the 'Etc/UTC' timezone set.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Looked up the '0070-tzdata' component source file and find that the process to
change timezone is:
 1/ echoing the timezone to the '/etc/timezone' file (ex: echo
"Europe/Paris">/etc/timezone )
 2/ call to the reconfiguration of tzdata package ( "dpkg-reconfigure -f
noninteractive -p critical tzdata" )

If I try to do the same thing by hand, I can se that:
 1/ echoing works fine (hopefully :) )
 2/ call to the tzdata package reconfiguration do not return any error, BUT the
'/etc/timezone' file content has been modified by the reconfiguration process.

I thought then the package tzdata was misconfigured or with errors. Looking up
the https://anonscm.debian.org/cgit/pkg-
glibc/tzdata.git/tree/debian/tzdata.config#n329 we can identify that the tzdata
configuration process override the '/etc/timezone' file if '/etc/localtime'
exists and is a symlink.
I really think I get something!

We may unlink '/etc/localtime' in
https://anonscm.debian.org/cgit/debian-live/live-
config.git/tree/components/0070-tzdata#n50
before calling 'dpkg-reconfigure ... tzdata'

Closes: 799359 816201 817831 824197
Changes:
 live-config (5.20160607) unstable; urgency=medium
 .
   * Team upload.
   * No longer manually start the getty@* services. There is systemd-logind
     already taking care of this at runtime when the user switches to the
     corresponding VT. Furthermore systemd-logind is smarter since it will
     avoid running it on an already used VT (such as vt1 which is nowadays
     used by gdm3). This also gets rid of the undesirable boot delay that
     was likely introduced by one of the above conflicts.
   * Make live-config-systemd the default backend.
   * Properly handle hwclock set to local time. Closes: #824197
     Thanks to Tom Jampen <tom@cryptography.ch> for the patch.
   * Fix timezone configuration by dropping /etc/localtime so that
     tzdata config script is forced to recreate it from /etc/timezone.
     Closes: #816201 Thanks to Gregory DAVID <groolot@groolot.net> for
     the analysis.
   * Also look for live/config.conf in /lib/live/mount/persistence/*/
     Closes: #817831 Thanks to Gregory DAVID <groolot@groolot.net>
     for the patch.
   * Automatically export variables set in live-config configuration
     files so that components inherit from them. Closes: #799359
     Thanks to Lukas Schwaighofer <lukas@schwaighofer.name> for the patch.
   * Drop override and options for XZ compression, it has been the default for
     a while.
   * Bump Standards-Version to 3.9.8.
