All I want is just a collection of #binutils, #GCC, #llvm+#clang, #glibc and #musl that are "free standing" / relocatable, which I can pack into a #squashfs image to carry around to my various development machines.

You'd think that for something as fundamental as compiler infrastructure with over 60 years of knowledge, the whole bootstrapping and bringup process would have been super streamlined, or at least mostly pain free by now.

Yeah, about that. IYKYK

#SquashFS 4.7 has been released (#SquashFSTools / #LinuxFS / #Linux / #FileSystem) https://github.com/plougher/squashfs-tools

Does anyone know how to run #Docker on #SquashFS ?
I've got an error: using mount program fuse-overlayfs: unknown argument ignored: lazytime
When I try to modprobe fuse it shows FATAL: Module fuse not found in directory

*The squashfs image is made on #Debian

@unascribed the one thing I'd like to be able to do with #squashfs is generate a multi-part fs, with each chunk a max of, say, 100GB, then be able to mount them later without needing to manually cat them all back together. maybe I haven't looked hard enough, but I can't see a way to do that

Klaus Knopper is a renowned German software developer, entrepreneur, and educator, best known for creating Knoppix, one of the first Linux distributions to run directly from a CD or DVD without requiring installation on a hard drive.

Как пересобрать ядро для WSL2 и остаться в живых

Мы активно пользуемся WSL2 для того, чтобы открывать линуксовые коры в Visual Studio. Для обеспечения консистентности символов и коры мы монтируем squashfs образ, созданный в целевой системе. После очередного апдейта целевого дистрибутива, у нас всё сломалось - squash монтировался, но мог посередине файла выдать ошибку чтения, записав в dmesg что-то типа SQUASHFS error: xz decompression failed

Ryan Does #NixOS - Part 7

I was able to generate the required files for #iPXE booting a #flake (#kernel + #initrd w/ #squashfs + iPXE script file), but kept running into issues with the kernel "unable to mount root fs" or "initramfs unpacking failed: invalid magic at start of compressed archive". What is weird is that https://github.com/nix-community/nixos-images/ when booted through netboot.xyz works just fine, if I grab the underlying kernel + initrd + iPXE script on MULTIPLE #systems , it fails with the latter message.

This is really boggling my mind as I thought there was data corruption happening, but I am more likely to believe something is happening within NixOS's #zstd compression, or with that building process.

Work has started on building the searchable archives of the RSS feeds in the Digital Post Office and it is about to adopt squashfs. The requirement is simple, a archive should be one file that contains many files, from which we can select files to extract as quickly as possible. Are there better alternatives for this?

#linux #archive #squashfs-tools

I was considering #SquashFS for my #server #backup and did a little #benchmark. The results are surprising!

Time it took to run `mksquashfs linux-5.18.15/` from RAM to the NAS in my lounge room via different remote file access methods (100 MBit/s link, ping 21ms, best out of 3 runs):
NFSv4 - 35.843s
SSHFS - 23.278s
NBD - 21.966s

I would've assumed that #NFS beats #SSHFS by a long shot!

I am just now getting time to write about this, but last weekend I went my local hacking space and got to hack a Tenda FH1206 router. It was a lot of fun! I definitely received some help on the soldering part though :blobcatsweats:

I also snagged a signed copy of Space Rogue! #security #hacking #router #squashfs #opensource

Для Linux предложена файловая система Composefs

#Linux #flatpak #composefs #squashfs

Александр Ларсон (Alexander Larsson), создатель Flatpak, работающий в компании Red Hat, представил предварительный вариант патчей с реализацией файловой системы Composefs для ядра Linux. Предложенная файловая система напоминает Squashfs и также подходит для монтирования образов в режиме только для чтения. Отличия сводятся к обеспечению в Composefs эффективного совместного хранения содержимого нескольких примонтированных дисковых образов и поддержке проверки подлинности читаемых данных. В качестве областей применения, в которых может оказаться востребована ФС Composefs, называется монтирование образов контейнеров и применение для Git-подобного репозитория OSTree.

Dear Internet, does anyone know of a reliable way to unmount and remount a #squashfs file-system with a script, without rebooting the server? Because I'm struggling to find one. RTs gratefully received! #linux #toot

#Superblocks are metadata structures within file systems, and as such you can bet on the fact that #squashfs has one or more superblocks.

ok so i want to setup myself an #ApacheJames #mailserver, on #FreeBSD, with mail repository store DBFile (headers in RDBMS, body in files), with the files being, from time to time, moved to a #squashfs archive — unionized with the recent ones using #unionfs.
