Hrmpf rescue system, built on Void Linux

Project name looks like it was inspired by Grml :-)

  Yeah first thing I thought. It also sounds like it overlaps in functionality. I've used GRML for rescue stuff for many years. But this might be interesting too. One thing I'd love to have is to preload since defaults into the image. Like launching an SSH Daemon with a given private key so I can fix a system without a monitor

    Iirc there was a time where grml just was not up to date anymore? I somewhat remember that it did not support btrfs at some point.
    - GekkePrutser 5y ago
      Could be, I never used btrfs. I do use ZFS heavily though, so that would definitely be a point for me. I see Hrmpf does have it so I'll check it out.
    - teddyh 5y ago
      Grml had a bit of a gap between the december 2018 release and the june 2020 release.

  In German "hrmpf" is an exclamation and expression of frustration, with a possible connotation of acceptance that something has indeed gone wrong. So it’s a very apt name for a rescue system :)

    The percentage of consonants in this word induces serious amounts of Angstschweiß :)

        "Blb vlk pln žbrnd zdrhl hrd z mlh Brd skrz vrch Smrk v čtvrť srn Krč." 7 years of study and this language still terrifies me.

        Ok... and here I was thinking that a single word without vowels in Slovenian (Trst, the Slovenian name of the Italian city Trieste) was remarkable. Guess I have to reconsider that...
        lproven 5y ago
        Yugoslavia was famed for its critical vowel shortage: https://www.ling.upenn.edu/~beatrice/humor/clinton-deploys-vowels.html https://www.ling.upenn.edu/~beatrice/humor/clinton-deploys-v... ... However, speaking as a resident of Czechia, it's worse here. Consider that quote. The word "čtvrť" means _quarter_, as in Latin Quarter or Arab Quarter. It differs from the word "čtvrt" (meaning a quarter of a pizza, say) by the half a diacritic on the final letter T: ť. That diacritic modifies the following vowel — for example the famous shoe company is not Bata (bar-ta) but Baťa (bar-tya). In "čtvrť" the háček modifies the following vowel that isn't there and thus changes the meaning of the word. Czech is czallenging.

  Both are German names, following the same specific sense of naming. And looking around, Hrmpf seems to get inspirations from Grml, maybe even is a clone with different foundation?

FYI this ships with zfs modules precompiled, if you're into that sort of thing. https://github.com/leahneukirchen/hrmpf/commit/dcc35b75676f3bd4617d9c5277c3bf182948bf7f https://github.com/leahneukirchen/hrmpf/commit/dcc35b75676f3...

  That is really useful. Having to build an archiso every time I accidentally pacman to a kernel version that breaks zfs is annoying. I’ve only done it twice but still.
  - boomboomsubban 5y ago
    Why not just build once and then keep the USB for emergencies?
    - mnd999 5y ago
      I mean I do keep them but they get too old eventually and then they won’t mount the pool, or will only mount it read-only.
      - boomboomsubban 5y ago
        Both ZFS updates and pacman breaking are rare enough that I forgot that would happen. Though using this rescue system would work, there's also a group that maintains a script to grab the correct ZFS module for a running archiso, might come in handy for you. https://github.com/eoli3n/archiso-zfs https://github.com/eoli3n/archiso-zfs

  Currently dealing with a zfs cachefile issue on my nas, where hrmpf has been instrumental in letting me backup data and regenerate a cachefile from my macbook.
opk 5y ago
I'll be taking particular note of this rescue system on the basis of the identity of the person who has created it. They're someone I've come across more than once in the open source world and definitely have respect for. I'd also recommend mblaze which is the primary tool I use for reading mail.

  Agreed, Leah is a great person and has been a boon to the Void community. In fact the entire Void team is full of amazing individuals, which is a big reason why it's (in my opinion) the best Linux distro overall.

How does this compare to SystemRescue ? Hrmpf has seen no release for the past 8 months https://github.com/leahneukirchen/hrmpf/releases https://github.com/leahneukirchen/hrmpf/releases where SystemRescue is updated regularly https://www.system-rescue.org/Changes-x86/ https://www.system-rescue.org/Changes-x86/ .
- Arch-TK 5y ago
  First off... It's a system rescue tool... Have there been any massive advancements in the state of the art of system rescue in the past 8 months that need to be integrated into this tool? Secondly, since this is void mklive based, whenever you run it, you get the current state of packages. This means that the actual programs are never really going to be out of date at time of building. The project would only need to be updated to update the few boot utilities which are included in the iso, or to update the LTS kernel included.
  - spijdar 5y ago
    To add a little to that second part, I'd say this is really meant to be "built on your own", following that brief example at the end of the README. The releases are more of a convenience thing. You will need Void's package manager XBPS installed, though. It can be harmlessly installed on other distros and won't (shouldn't?) interfere with the host package manager.

    - CameronNemo 5y ago
      Yep xbps can be installed on other distros without causing issues. I believe the void project even distributes static musl binaries.
anthk 5y ago
Good. On games, I'd add a SDL-less build of Frotz with some z-machine libre games such as Dungeon or All Things Devour. Also, a cgames package for Void would be nice, csokoban it's perfect to play on slow recovering. I'll add ffmpeg, sox and visidata too as they are the perfect suite for media and office suite files. MPV and Mplayer work on the framebuffer, too. Optional dependencies for visidata: https://www.visidata.org/docs/formats/ https://www.visidata.org/docs/formats/ Finally another must have tool: gnuplot and calc. Because often you need to do some graphs and calculations. And maybe bitlbee listening on localhost, with libpurple support. IM and IRC'ing for support it's unvaluable. Oh, a quick and dirty ebook reader, with unzip and lynx: #/bin/sh unzip -qcp "$1" "*ml" "*.htm" | lynx -force-html -dump -stdin -nolist | less -r -M +Gg

Good. On games, I'd add a SDL-less build of Frotz with some z-machine libre games such as Dungeon or All Things Devour. Also, a cgames package for Void would be nice, csokoban it's perfect to play on slow recovering. I'll add ffmpeg, sox and visidata too as they are the perfect suite for media and office suite files. MPV and Mplayer work on the framebuffer, too.
