Systemd Service Hang

Why and when do systemd services hang indefinitely

 Posted on April 22, 2022  |  3 minutes  |  482 words  |  Ritesh Raj Sarraf

Finally, TIL, what can all be the reason for systemd services to hang indefinitely. The internet is flooded with numerous reports on this topic but no clear answers. So no more uselessly marked workarounds like: systemctl daemon-reload and systemctl-daemon-reexec for this scenario. The scene would be something along the lines of: rrs 6467 0.0 0.0 23088 15852 pts/1 Ss 12:53 0:00 | | \_ /bin/bash rrs 11512 0.0 0.0 14876 4608 pts/1 S+ 13:18 0:00 | | | \_ systemctl restart snapper-timeline.

Wayland KDE X11

Impressions from KDE, Wayland and Plasma 5.21.1

 Posted on February 26, 2021  (Last modified on March 1, 2021)  |  6 minutes  |  1093 words  |  Ritesh Raj Sarraf

KDE Impressions These days, I often hear a lot about Wayland. And how much of effort is being put into it; not just by the Embedded world but also the usual Desktop systems, namely KDE and GNOME. In recent past, I switched back to KDE and have been (very) happy about the switch. Even though the KDE 4 (and initial KDE 5) debacle had burnt many, coming back to a usable KDE desktop is always a delight. [Read More]

Linux and ARM With more ARM based devices in the market, and with them getting more powerful every day, it is more common to see more of ARM images for your favorite Linux distribution. Of them, Debian has become the default choice for individuals and companies to base their work on. It must have to do with Debian’s long history of trying to support many more architectures than the rest of the distributions. [Read More]

Device Mapper Multipath status in Debian

 Posted on December 29, 2015  |  3 minutes  |  478 words  |  Ritesh Raj Sarraf

For Debian Jessie, the multipath support relied on sysvinit scripts. So, if you were using systemd, the level of testing would have been minimal. At DebConf15, I got to meet many people whom I’d worked with, over emails, over the years. With every person, my ask was to use the SAN Storage stack in a test environement, and report bugs early. Not after the next release. This applies also to the usual downstream distribution projects. [Read More]

Controlling ill behaving applications with Linux Cgroups

 Posted on October 20, 2015  |  7 minutes  |  1340 words  |  Ritesh Raj Sarraf

For some time, I have been wanting to read more on Linux Cgroups to explore possibilities of using it to control Ill behaving applications. At this time, while I’m stuck in travel, it has given me some time to look into it. In our Free Software world, most of the things are do-o-cracy, i.e. when your use case is not the common one, it is typically you who has to explore possible solutions. [Read More]

Laptop Mode Tools - 1.68

 Posted on August 27, 2015  |  2 minutes  |  225 words  |  Ritesh Raj Sarraf

I am please to announce the release of Laptop Mode Tools, version 1.68. This release is mainly focused on integration with the newer init system, systemd. Without the help from the awesome Debian systemd maintainers, this would not have been possible. Thank you folks. While the focus now is on systemd, LMT will still support the older SysV Init. With this new release, there are some new files: laptop-mode.service, laptop- mode. [Read More]

Micro DD meetup

A couple of us DDs met here on the weekend. It is always a fun time, being part of these meetings. We talked briefly about the status of Cross Compilation in Debian, on the tools that simplify the process. Next we touched upon licensing, discussing the benefits of particular licenses (BSD, Apache, GPL) from the point of view of the consumer. The consumer being an individual just wanting to use/improve software, to a consumer who’s building a (free / non-free) product on top of it. [Read More]
