[arch-projects] [PATCH 1/2] rc.shutdown: reorder a bit
by Tom Gundersen 14 Nov '11

14 Nov '11

The new ordering is now: 1) book-keeping 2) shutting down and killing processes 3) swapoff 4) unmounting and tearing down of block devices The reason to move 1) to the top is so it will not interfere with the killing of processes. The reason for not moving 3) to the top as well is that we want to minimize the amount of stuff that has to be moved from swap to ram. However, swapoff must happen before 4) as we don't know what is under the swap device/file. Added a TODO: unmount any devices backed by swap (tmpfs/ramfs) to make sure that their contents is thrown away rather than moved to ram. In principle we might get OOM on shutdown due to the current situation, but in most cases the only problem should be that shutdown is unecessarily slow. Thanks to Dan and Dave for prompting me to look into this.

Why not make use of the `name` cgroup in same way systemd does? Then you can simply: kill $(</path/to/cgroup/tasks) ... in a loop for a couple iterations as needed. C Anthony

[arch-projects] [initscripts] [GIT] Arch Linux initscripts repository branch master updated. 2011.10.2-6-g00070ec

This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "Arch Linux initscripts repository". The branch, master has been updated via 00070eca730dec9c6d587cc1639f6abaca83fa34 (commit) via fbff8c64e2be9cbb24bd7f824552842d0bd6442d (commit) via 1fdaa33f06786231da3b86e5d8b646b46f6ca1f9 (commit) via e46ee7e6c9fbbd8d21c306719170ae086cf12761 (commit) via 697aa90c7eede255635f9c6d2e7fe12338aa2886 (commit) via 559175f82d6320af8855c34b7e4b9b3cb4a3ad9a (commit) from 750db158fca0681273b65b354716469168e341c1 (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- commit 00070eca730dec9c6d587cc1639f6abaca83fa34 Author: Tom Gundersen <teg(a)jklm.no> Date: Wed Oct 26 23:11:20 2011 +0200 minilogd: kill This is not very useful, is not maintained, has open serious bugs. Better to admit that it does not work and just remove it. Someone could easily make an AUR package with a hook, if they want it and can make it work as expected. The only case where this would be useful is in case lvm monitoring is in use and dmeventd sends out a message to syslog before syslog-ng is started (there is a very small window). However, not even this works atm (as far as I know) due to bugs in minilogd.

[arch-projects] [PATCH] [devtools] Have signature checking work in chroots

[arch-projects] [devtools] [PATCH] commitpkg: Sync changelog/install check with makepkg(8)
by Lukas Fleischer 24 Oct '11
