Here are my teaching guix videos
Hello, I've been recording myself tweaking Guix and various other things and posting the videos here: https://video.hardlimit.com/accounts/joshua_branson/video-channels Please note that I do not describe myself as a guix developer. I am a guix user, who occasionally does tiny bug reporting and documentation patches. If you are something of a guix newbie, then you may find these videos helpful. If you are an experienced guix developer, would you please consider posting a video of your developmental workflow. Because I am certain that I could learn a lot from the more experienced guix developers. Thanks, Joshua P.S. Please send replies to the list and NOT my inbox. I am subscribed to help-guix. Thanks.

Maybe we can ask the kernel devs to improve the error reporting here.
Re: Guix System ext4 index full
Vincent Legoll 写道： I think the filesystem (or directory) is full of inodes. No, but it's a similar hard limit, and one that not even ‘df -i’ will warn you about. Ext4's dir_index feature uses hash tables to look up directory entries, so that for directories with a very large number of items (like /gnu/store!), the kernel doesn't have to do the horribly slow equivalent of: for i in *; do …; done Unfortunately, once that hash table fills up, the premier stable Linux file system just… gives up and refuses to write any more data. In a very cryptic way. The large_dir flag ‘increases the limit’ (the man page does not say by how much) but it doesn't go away.

Guix System ext4 index full
Dear Guix, I'm running Guix System and I'm getting the following messages in dmesg: [42457.660237] EXT4-fs warning: 7076 callbacks suppressed [42457.660240] EXT4-fs warning (device sdd3): ext4_dx_add_entry:2335: Directory (ino: 19796947) index full, reach max htree level :2 [42457.660242] EXT4-fs warning (device sdd3): ext4_dx_add_entry:2339: Large directory feature is not enabled on this filesystem [42457.697840] EXT4-fs warning (device sdd3): ext4_dx_add_entry:2335: Directory (ino: 19796947) index full, reach max htree level :2 [42457.697842] EXT4-fs warning (device sdd3): ext4_dx_add_entry:2339: Large directory feature is not enabled on this filesystem [42457.697930] EXT4-fs warning (device sdd3): ext4_dx_add_entry:2335: Directory (ino: 19796947) index full, reach max htree level :2 [42457.697931] EXT4-fs warning (device sdd3): ext4_dx_add_entry:2339: Large directory feature is not enabled on this filesystem [42457.702879] EXT4-fs warning (device sdd3): ext4_dx_add_entry:2335: Directory (ino: 19796947) index full, reach max htree level :2 [42457.702880] EXT4-fs warning (device sdd3): ext4_dx_add_entry:2339: Large directory feature is not enabled on this filesystem [42457.703994] EXT4-fs warning (device sdd3): ext4_dx_add_entry:2335: Directory (ino: 19796947) index full, reach max htree level :2 [42457.703995] EXT4-fs warning (device sdd3): ext4_dx_add_entry:2339: Large directory feature is not enabled on this filesystem I used the graphical installer to install the Guix System. Also, I cannot write to the root filesystem because the system thinks it's full (while df shows it has ~125G free space). Any help would be appreciated. Kind regards, Roel Janssen

The reason 'guix build foo' gives a different result is because you have not run 'guix pull', so you are using the "guix snapshot" from gnu/packages/package-management.scm, which is on a fixed commit. Whereas when you built the VM, you were likely using a newer version of Guix. > How to properly export local definitions in the > virtual machine image ? There are a couple of ways around this. One is to run 'make update-guix-package' in the Guix source tree to update the Guix snapshot, and use './pre-inst-env' when generating the VM. It requires a Guix development setup though. Another is to look at the commit that was used to generate the VM in /run/current-system/provenance and run 'guix pull --commit=that-commit'. Perhaps 'guix system vm-image' could learn a '--update-guix-snapshot' to automatically update the "system guix". Someone would have to implement it first though. :-) HTH, Marius signature.asc Description: PGP signature

Guix checks for the availability of substitutes, so you don't have to spend hours building something that was already built. Of course you can disable substitutes (--no-substitutes) or specify another substitute server if you wish (--substitute-urls). HTH!
Re: newbe question
Adam Kandur via writes: > why when i "$ guix pull" i need to connect to ci.guix.gnu.org? ci.guix.gnu.org provides you with binaries, so that you don’t have to build everything from source. By default Guix will fetch from ci.guix.gnu.org, but you don’t have to download anything from ci.guix.gnu.org if you don’t want to. You can download from any other machine that runs “guix publish” or contact the upstream servers directly to fetch source code and build everything locally. -- Ricardo

Local definitions and Virtual machine image
Hello Guixers ! I created an image with 'guix system vm-image' which contains local defined packages. These packages are present on the Virtual Machine however they are not listed with 'guix package --list-installed'.As I need to customize LD_LIBRARY_PATH, I use "guix build" to list store directories from package names but it tries instead to recompile them even though they are already installed. How to properly export local definitions in the virtual machine image ? Best regards, Emmanuel Medernach
