marvin	f931705971	Add --mount flag for 9p host directory sharing ... Add support for sharing host directories into the VM via QEMU 9p (virtio-9p). The --mount flag can be repeated; each host directory appears at the same absolute path inside the VM. Design: - QEMU: each --mount gets a short 9p tag (slim0, slim1, …) via -virtfs local,path=…,mount_tag=slimN,security_model=mapped-xattr. Tags are kept short because 9p mount_tag has a ~31-byte limit. - Kernel cmdline: the full destination path is passed as slim.mount=<tag>:<base64(path)> so the init script knows where to mount each tag. Base64 avoids issues with spaces/special chars. - slim-init.sh: after networking, parse slim.mount= entries, mkdir -p the destination, and mount -t 9p <tag> <dest> -o trans=virtio,version=9p2000.L Tests verify: 9p share detection via sysfs mount_tag, 9p entry in mount output, file content accessible at the expected path, and clean VM exit.	2026-09-10 00:18:38 +02:00
hulthe	c2a9f00fc0	Inject universal /slim/init instead of requiring container-specific setup ... slim now works with any Containerfile by injecting distro-agnostic scripts at build time: - /slim/init: mounts special filesystems, configures networking (static QEMU slirp), sets up cgroup2, timezone, and rootless container prereqs. Parses slim.cmd=<base64> from the kernel cmdline for runtime overrides, otherwise execs /slim/exec. - /slim/exec: generated from the image's CMD/ENTRYPOINT (via podman image inspect), overridable via --cmd at build and run time. Changes: - New src/inject.rs: inspect image config, infer command, generate /slim/exec script, inject /slim/ into mounted rootfs - New src/scripts/slim-init.sh: the universal init script (include_str!) - build.rs: rename --init to --cmd, inject scripts before packing, drop Meta::save, restructure to ensure unmount always runs - qemu.rs: hardcode init=/slim/init, add --cmd (base64 on cmdline), drop Meta::load, add -no-reboot - Remove src/meta.rs and meta.toml (no longer needed) - Cargo.toml: add serde_json + base64, remove unused walkdir + cpio + toml - Example Containerfiles simplified to plain FROM + CMD - New example/test.sh for manual verification - README updated for new workflow	2026-09-08 21:58:01 +02:00
