Dracut: Discussion about future plans for bootloader and initramfs en Harald Hoyer

  • fallback strategies for non working boot entries
  • initramfs image with kernel modules in kernel rpm?
System vs Session - Lessons learned en David Zeuthen A recent trend in Linux is to read configuration and policy from the users login session instead of system-wide configuration. For example, instead of a system-wide power management daemon reading configuration and policy directives from somewhere in /etc, the system relies on a per-user daemon reading configuration and policy directives from the native desktop configuration store (e.g. GConf or GSettings/DConf). This presentation will examine the implications of this paradigm shift and point out where we lost/gained functionality and flexibility - and where we can still improve!

FAQ

  • Q: Do I have to do my presentation in English?
  • A: Nope, it's up to you. We're expecting some foreigners and visits from Red Hat to come, but if you don't feel comfortable doing the presentation in English, do it in Czech/Slovak
  • Q: So what kind of conference is it going to be? Like every other Linux conference?
  • A: No! The plan is to have a conference for developers, admins and testers, eg. not average Linux users, but for skilled Linux users who are either administering some servers, deploying services on Linux or developing apps on Linux
  • Q: How long does my presentation or session have to be?
  • A: Anylong from 30minutes up to one hour, workshops will probably be longer. We'll prepare a schedule apx a month before the event, at that time you'll be asked for time estimate.


Lodging

  • Hotel Avanti - closest hotel, 5-10 minutes of walking to University
  • Hotel Vista (formerly known as hotel Imos) - cheaper option, apx 20minutes by public transport far from University

Travel

to Brno, Czech Republic

There are several airports around Brno; http://whichbudget.com can be used to see which budget airlines operate flights to a destination; for your convenience, the airport names below are linked there; http://skyscanner.net can help you finding non-direct connections. For information about booking the train or bus tickets, follow the links in the rightmost column.

Airport (code, people transported/year) Distance from Brno By bus (time, price one way) By train (time, price/price back Detailed instructions
Brno (BRQ, 0.5 mil.) 0 km
Bratislava (BTS, 2 mil.) 130 km 2:30 EUR 9 2:00, EUR 9 (return EUR 13) Bratislava -> Brno
Wien, Vienna (VIE, 18 mil.) 150 km 2:40, CZK 310 (EUR 12.70) 1:40, EUR 27/EUR 9 Vienna -> Brno
Prague (PRG, 13 mil.) 210 km 2:30, CZK 200 or 150 (EUR 8.20 or 6.15) from 2:45 to 3:30, CZK 314/175 (EUR 12.80/7.15) Prague -> Brno

Note: the times include the time needed to get from the airport to the railway or bus station.

There are no relevant return discounts for trains, and the budget airlines often offer no return discount as well, so there is little incentive to use the same airport for both direction. Thus it might be a good idea, for example, to visit Vienna during your return journey; for details, see Vienna -> Brno.
