You can look for the Emacs executable currently present in your Guix profile by looking into the ~/.guix-profile/bin directory. It's small enough that you can explore it with a file manager, unlike /gnu/store. It's also simple to check from a terminal, for example with the command “ls -l ~/.guix-profile/bin/emacs”. >> I want to change the command for opening emacs in the starter,now >> version 27.2 change into emacs 28.

This can be done more easily with a menu editor such as ‘kmenuedit’ in KDE. I don't know what the Mate equivalent would be. A quick web search suggests there are both ‘Alacarte’ and ‘Mozo’ but it looks like neither of them are packaged in Guix unfortunately. > It's "just" a matter to refresh your graphical menu an usually we need > to logout and login (at least on a foreign distro) > >> 3.

If you change anything at all about the file/package or how it is produced, then the identifier changes as well. This helps Guix provide its reproducibility properties. -- Thanks Thiago

If I'm reading that correctly, that's the same distribution not found error. I
like your thought of python versus python3. However, the PySide2 package on
PyPI has a release for python2. If the build system were using python2, I
would expect it to download that and then fail.
How to install guix system from existing linux with guix package manager?
How would I install Guix system from an existing Linux that has the guix package manager on it (aka from a foreign distro)? Specifically I have Guix installed on Arch Linux on an encrypted btrfs ssd. I have a @home subvolume mounted on /home. Currently /gnu/store is not a subvolume, but I'd like to reuse it for guix system. I also have the efi system partition for uefi boot. What I'd like to do is install Guix system and boot from a subvolume. Ideally the guix fstab would be like this: @guix-root is mounted on / on guix system @gnu-store is mounted on /gnu/store on guix system and shared between arch and guix @home is mounted on /home and shared between arch and guix So I think the steps are as follows: 0. backup data (just in case) 1. move /gnu/store to subvolume 2. install Guix system manually with the following file systems: (mapped-devices (list (mapped-device (source (uuid "my-uuid")) (target "cryptroot") (type luks-device-mapping (file-systems (append (list (file-system (device (file-system-label "cryptroot")) (mount-point "/") (type "btrfs") (options "subvol=@guix-root") (dependencies mapped-devices)) (file-system (device (file-system-label "cryptroot")) (mount-point "/gnu/store") (type "btrfs") (options "subvol=@gnu-store") (dependencies mapped-devices)) (file-system (device (file-system-label "efi")) (mount-point "/boot/efi") (type "vfat"))) %base-file-systems)) 3. configure uefi to boot guix grub by default WDYT? any tips/suggestions?

For the record, this bug (dismissing the ‘keys’ argument) was introduced
in b4b2bbf4fb74c9f3e93d64863ab9b38957494b49 (Oct. 2021).
How come nobody noticed then?
The reason is that starting from
b4b2bbf4fb74c9f3e93d64863ab9b38957494b49, ‘authorized-key-directory’
would create an empty directory. That directory would then be copied by
‘openssh-activation’ to /etc/ssh/authorized_keys.d; since
/etc/ssh/authorized_keys.d would typically already contain the relevant
keys, nothing bad would happen.
Oleg’s commit 1f29ed4a812f86c45e2d9c37fd9f80f6d0418293 introduced
another bug though: we’d create an authorized-key directory that
included keys brought by extensions, but each of these files would be
empty (because ‘extend-openssh-authorized-keys’ would dismiss key files
associated with user names), which could lock yourself out.
Fixed in 0dc63ce519c5f98b2186d1871176e2fac3a6926b. Reconfiguration
recommended before you’re locked out!
Thanks,
Ludo’.
