distrobox: Opening Images in Native GIMP from IrfanView Running Under Wine in Distrobox

I use IrfanView via Wine inside a Distrobox container and wanted its external editor feature to open images directly in native GIMP. IrfanView passes the image path in Windows format (Z:\home\home-folder\Pictures\photo.jpg), so a small Python script handles the conversion and launches GIMP. Sounds simple. It wasn't.

Two things needed fixing before GIMP would even start. First, GIMP's sandboxed image loader (glycin) uses bubblewrap, which cannot create user namespaces inside a container — fixed with GLYCIN_DISABLE_SANDBOX=1. Second, any process launched from the script died the moment the script exited, because Wine kills all child processes when its own child (the Python script) returns.

Even after solving those, GIMP crashed every time it tried to open a file, with a GTK3 assertion failure inside GtkFileChooserWidget. The same command worked perfectly from the shell. The environment variables were identical. The difference turned out to be invisible to env: Wine installs a seccomp filter on its processes, and that filter is inherited by every child process across fork and exec. No amount of environment tweaking or session detachment can clear an inherited seccomp filter. GTK's file chooser widget makes a syscall during initialisation that Wine's filter blocks, and GIMP crashes.

The fix is to launch GIMP as a transient systemd user service with systemd-run --user --no-block. A process started this way is owned by systemd, not Wine — clean process state, no inherited seccomp filter, completely outside Wine's process tree.

#!/usr/bin/python
import os, sys, subprocess

def convert_wine_path(p):
    return p.replace('\\', '/').replace('Z:', '')

env = os.environ.copy()
img_file = convert_wine_path(sys.argv[1]) if len(sys.argv) == 2 else None

cmd = [
    'systemd-run', '--user', '--no-block',
    '--setenv=GLYCIN_DISABLE_SANDBOX=1',
    f'--setenv=DISPLAY={env["DISPLAY"]}',
    f'--setenv=HOME={env["HOME"]}',
    f'--setenv=XDG_RUNTIME_DIR={env["XDG_RUNTIME_DIR"]}',
    '/usr/bin/gimp'
]
if img_file:
    cmd.append(img_file)

subprocess.run(cmd)


Save it somewhere on your Linux filesystem, point IrfanView's external editor to the Z: path equivalent, and it works. The same trick applies to any native Linux app you need to launch cleanly from within Wine.

gentoo: There was an error during CUPS operation: "No such file or directory".

This happend for me with gentoo, cups and hplip. Had to install filters:
emerge --ask net-print/cups-filters End then
systemctl restart cups

gentoo and distrobox: OCI runtime exec failed: exec failed: unable to start container process: error starting setns process: exec: already started

I have gentoo host, with systemd, nvidia and docker. When I want to create a distrobox image with systemd in the container, e.g.:
distrobox create --nvidia -i archlinux -n abox -H ~/home-abox --init --additional-packages "systemd"
I was getting: OCI runtime exec failed: exec failed: unable to start container process: error starting setns process: exec: already started
The solution was to use crun container runtime, instead of default runc. To do this

1. Install crun: emerge -av app-containers/crun
2. Create `/etc/decker/daemon.json` with the content: {
"runtimes": {
"crun": {
"path": "/usr/bin/crun"
}
},
"default-runtime": "crun"
}
3. Restart docker sudo systemctl restart docker

bedrock linux: share getnoo's /etc/portage with stratas

For example file managers install in strta, e.g. mc, yazi, will not be able to go /etc/portage of gentoo. To fix that, share portage folder in

Add portage to [global] in /bedrock/etc/bedrock.conf: etc = adjtime, crypttab, default/grub, fstab, group, group+, group-, group.OLD, group.org, gshadow, gshadow+, gshadow-, gshadow.OLD, gshadow.org, hostname, hosts, login.defs, machine-id, modprobe.d/blacklist.conf, passwd, passwd+, passwd-, passwd.OLD, passwd.org, rc.local, resolv.conf, resolvconf/run, shadow, shadow+, shadow-, shadow.OLD, shadow.org, sudoers, portage
Then sudo brl apply
