Re: Installer of Debian Stable allows to use btrfs for /, does it mean it's mature enough to use safely?

I have severe allocation issues in btrfs with recent kernels and
recent btrfs-tools when using thousands of snapshots. All the
community had to offer was "well, try to restrict yourself to at most
a few hundred snapshots".

btrfs rebalance brings the whole system to a halt until it has
finished, since it places some kind of lock on the file system. The
effect on the system's other seervice is severe up to "sit back and
wait until system becomes responsive again".

That's not what I'd call production ready. It's simply just betafs at
the moment.


Thank you very much for your experience report, that helps me a lot
in staying away from btrfs for a while longer. Which is a shame,
because I really like the ideas behind it and the features it has,
but I don't want to spend endless time with filesystem maintenance.
This confirms that I should wait longer before giving it a try.

Status of fedmsg for the Debian infrastructure

Hello,

in the QA BoF at DC16 fedmsg was briefly mentioned, and I only found
[0], but could not find out what happened to the project. Has somebody
some more information about this?

Thank you!

Re: [RFC] Switching dpkg-deb --uniform-compression by default

[Cyril Brulebois]

Hi,

Guillem Jover  (2016-07-06):

> so that both control.tar and data.tar members use the same
> compression, which currently would be xz (or gzip with -Zgzip).

(AFAICT 'none' is still supported, contrary to 'bzip2' and 'lzma').

That wouldn't seem crazy to me.

[ Adding debian-boot@, where “the d-i people” are, and debian-cd@ for
  completeness. ]

A few years ago we pushed for xz compression in some key packages to try
and squeeze more packages into installation images, notably CD#1; ISTR
that would only change the data part and not the control one, which
would limit the size gain for some specific packages. debian-cd only
generates netinst CDs nowadays so that's no longer a hot topic for us
AFAIK.

> Not all .deb parsers support control.tar.xz yet, but most do:
> 

udpkg's status there seems correct (supports gz/xz/no compression), and
just to be sure: I've just checked that compression_type is indeed
handled independently for control (in udpkg.c's dpkg_unpackcontrol) and
for data (dpkg_dounpack).

> Would there be any objections to this?

Bottom-line from a d-i point of view: having both compression in sync by
default shouldn't change anything on our side (shouldn't gain us much
but shouldn't do much harm either).
