Re: [Freedombox-discuss] Debian plan to drop support for Raspberry Pi and Dreamplug?

 I believe proposal is not to drop the armel port entirely, but trim
 it to no longer support _smallest_ devices.

That might be better, unless Dreamplug is one of those.  The - jessie
supported: - [proposed dropping] comment was not too clear for me,
but it indicated that all armel archs supported in wheezy was planned
to be dropped in Jessie.  I guess I overlooked the link.

 You are correct that Neither Raspberry Pi nor Dreamplug can run on
 Debian armhf port (Dreamplug is ARMv5 that has no support for
 hardfloat, whereas Raspberry Pi is ARMv6 specifically supporting
 hardfloat but the Debian port has other features enabled too that
 are only supported in ARMv7 onwards).

Right.

You quoted a lng text containing several links.  I guess you mean 
the link in the section you emphasized:

https://lists.debian.org/debian-arm/2013/06/msg00206.html

No, I did not overlook that link - and in fact I thought you did, 
because it points to a mail with the title Dropping support for the 
smallest armel machines which discusses specifically the iop32x, ixp4xx 
and orion5x kernel flavors.

Dreamplug uses kernel flavor kirkwood.

I don't know which kernel flavor Raspberry Pi uses - if any flavor 
supported by Debian at all.

Do anyone actually use Debian (instead of the unofficial fork optimized 
for ARMv6) for Raspberry Pi?

Anyone has some measurements on running either system on Raspberry Pi?

Correct.

 supported by Debian at all.

Supposedly it can run one of the currently-stock Debian armel kernels,
but it won't make best use of the floating point hardware.

I haven't tried it yet, but I intend to soon.

  https://wiki.debian.org/RaspberryPi

I've also seen quite a bit of discussion at various times about what it
would take to properly support Raspberry Pi in Debian.  The persistent
need for a binary blob to boot seems problematic to me, but it's likely
something that could be finessed in the installer similarly to how we
currently handle user-supplied binary driver modules?

Re: [Freedombox-discuss] LDAP

Jonas Smedegaard d...@jones.dk writes:

 Ok.  Makes good sense to mandate use of shared auth mechanism.  Not 
 convinced LDAP is the ideal for that, though.

It probably isn't, but I don't know of anything better.  Note that I
traded emails in Feb with Howard Chu about using LDAP in this local-only
way, and he strongly suggested we create an optimized build of openldap
with a smaller footprint than the Debian standard build.   

Clearly not critical path, but this is another possible task for someone
out there reading who would like a modest project that could help us out
in the long term.

 It is of *big* importance to me that we do *not* move storage from /etc 
 to a database: It may seem tempting to use that approach when needing a 
 setup different from what the corresponding package maintainer offers, 
 but since we have *no* administrator on our systems, our setup *must* be 
 supported by package maintainers.

I agree.

What I think we can effectively use LDAP for is to manage the information
associated with identities.  Users, what access rights they should have,
etc, in an application-neutral way that we can potentially wrap some
plinth UI goodness around eventually.

Re: [Freedombox-discuss] Dev: New FreedomBox-Setup Dependency: NTP

2013-12-04 Thread Bdale Garbee
Petter Reinholdtsen p...@hungry.com writes:

 I am very found of NTP and correct clocks.  And in an earlier version
 (a few weeks ago) of freedombox-setup, ntp was part of the
 installation set.  But I decided to take it out until it was properly
 discussed, as it will create a regular beakon out of any freedombox
 machine. 

I think it's important to include.  A UI switch to disable it if the
user really wants to seems reasonable to include.  Managing the set of
peers / servers the box trades time information with when turned on
seems like the right place to focus most of our configuration attention?

At our meeting in Eben's offices in Feb, dkg came up with really cute
hack for setting the system time in an initial set-up script by
acquiring the client system's sense of time from I think an SSL session
initiation packet.  I'm not aware of that ever being publicly documented
or implemented in our stack, but it seemed like a really neat hands
off way to handle the set-the-time-on-first-boot problem without
relying on centralized infrastructure.

 The persistent

I happened to learn recently that full open-sourcing of the GPU blob
for the Pi seems very likely to happen soon, so this may not be an
issue for much longer :-)
