Far too much..in what kind of system .. do you have harddisks from
the 90's ? in 2011, the average *consumer* hard drive was 590 GB..
increasing size at a rate of 39% per year.

How ignorant and blind are you ...

Journalctl showing the logs with 2K/s - that's 60's style

In 2013 systemd-journal (the default in most distros :) needs a week to
show such a 1.3G journal ... it can't even handle 90's file sizes but
you complain that users don't always want to keep their / small.


vm servers are hosting dozens or hundreds of journald "powered" systems.
They all need much more space / network bandwidth / traffic / time /
energy to backup.

This is one of our typical productive openSUSE 11.4 installations:
Filesystem Size Used Avail Use% Mounted on
rootfs 3.0G 1.1G 1.8G 38% /
devtmpfs 243M 88K 243M 1% /dev
tmpfs 246M 4.0K 246M 1% /dev/shm
/dev/vda1 3.0G 1.1G 1.8G 38% /

Upgrading to journald per default means either only keeping logs for a
few last days or double hd space.

We have rpmlint complaining about a few KB documentation in non-doc
packages (and much more similar warnings). Not even significant when
journald is in use. But not allowed to complain about a journal wasting
giga bytes?

Even you always try to convince us that that tmpfs (maybe < 4-8GB on
average systems) are enough /tmp for everybody. How does this
match? /var/log has to be 201x style but /tmp must be 90' style?

We have still many NFS client desktops with <80GB HD where / is ~20GB
(90% full) and thre rest is local /tmp storage for the developers and
number crunchers. Each wasted GB would be painful for our users and
then for our NFS server.



The same

as compressed text files would be probably about 20M (factor 60!).

The journal is already compressed (XZ is used.. ) it is of course
much bigger than a text file because it has metadata attached.

Haha.
