-### Testing with composefs (sealed images)
+### Building and testing with the composefs backend
 
-To build and test with the experimental composefs backend:
+bootc has two storage backends: `ostree` (default, production) and `composefs`
+(experimental). The composefs backend has several axes of configuration:
+
+| Variable | Values | Notes |
+|---|---|---|
+| `variant` | `ostree`, `composefs` | Storage backend |
+| `bootloader` | `grub`, `systemd` | systemd-boot required for UKI |
+| `boot_type` | `bls`, `uki` | UKI embeds the composefs digest |
+| `seal_state` | `unsealed`, `sealed` | Sealed signs the UKI for Secure Boot |
+| `filesystem` | `ext4`, `btrfs`, `xfs` | xfs lacks fsverity, incompatible with sealed |
+
+These are controlled via `BOOTC_`-prefixed environment variables.
+Using environment variables (rather than `just` command-line overrides)
+is recommended because they persist across commands in the same shell
+session — so `just build` followed by `just test-tmt` will use the
+same configuration:
 
 ```bash
-# Build a sealed image with auto-generated test Secure Boot keys
+# Set up a composefs development session
+export BOOTC_variant=composefs
+export BOOTC_bootloader=systemd
+# Now all just targets use these settings:
+just build
+just test-tmt readonly
+just test-container
+```
+
+The constraints are:
+
+- `sealed` requires `boot_type=uki` (the digest lives in the UKI cmdline)
+- `sealed` requires `filesystem` with fsverity support (`ext4` or `btrfs`)
+- `uki` requires `bootloader=systemd`
+
+Common workflows:
+
+```bash
+# Simplest composefs build (unsealed, grub, BLS, ext4)
+export BOOTC_variant=composefs
+just build
+
+# Composefs with systemd-boot
+export BOOTC_variant=composefs BOOTC_bootloader=systemd
+just build
+
+# Fully sealed image (systemd-boot + signed UKI + Secure Boot)
+# This is the most common composefs dev workflow:
 just build-sealed
 
-# Run composefs-specific tests
-just test-composefs
+# Run composefs integration tests (all four params are required)
+just test-composefs systemd ext4 bls unsealed
+
+# Run sealed UKI tests
+just test-composefs systemd ext4 uki sealed
 
-# Validate that composefs digests match between build and install views
+# Validate composefs digests match between build and install views
 # (useful for debugging mtime/metadata issues)
 just validate-composefs-digest
 ```
 
-The `build-sealed` target generates test Secure Boot keys in `target/test-secureboot/`
-and builds a complete sealed image with UKI. See [experimental-composefs.md](docs/src/experimental-composefs.md)
-for more information on sealed images.
+The `build-sealed` target generates test Secure Boot keys in
+`target/test-secureboot/` and builds a complete sealed image with all
+the sealed composefs settings. See
+[experimental-composefs.md](docs/src/experimental-composefs.md) for
+more information on sealed images.

 Note that regenerating the initramfs is required when changing this file.
 
+<!-- TODO: root.transient-ro is not yet handled by bootc's Rust code.
+     The upstream ostree C code (ostree-prepare-root) fully supports both
+     root.transient and root.transient-ro as separate keys, with mutual
+     exclusion and implicit root_transient=TRUE when transient-ro is set.
+     bootc's Rust side needs updates in three places:
+
+     1. crates/ostree-ext/src/ostree_prepareroot.rs — overlayfs_enabled_in_config()
+        only checks root.transient, not root.transient-ro. A config that sets only
+        transient-ro=true without composefs.enabled will produce a false-negative
+        in the baseimage-composefs lint.
+
+     2. crates/initramfs/src/lib.rs — RootConfig only has a `transient: bool` field.
+        It needs a `transient_ro: bool` field with #[serde(rename = "transient-ro")]
+        and the composefs-native boot path must handle it (read-only overlayfs upper).
+
+     3. crates/lib/src/lints.rs — no lint validates or warns about the transient-ro
+        key; the existing composefs/overlayfs lint should be extended.
+
+     Note: changing prepare-root.conf requires initramfs regeneration at container
+     build time, so the fix must also account for that in any lint messaging.
+-->
