patches: A:/t windows root + TEBAKO_MOUNT_ROOT run-time override - #51
Merged
Conversation
… 5 series) Owner-final: the windows memfs root is A:/t (MAX_PATH headroom on every in-image path), reverting the A:/__tfs__ uniformity pass (#49). And the root is no longer only baked: rbconfig now emits CONFIG["prefix"] = ENV["TEBAKO_MOUNT_ROOT"] || '<baked>' (posix + msys variants, prefix + RUBY_EXEC_PREFIX), so a boot-time TEBAKO_MOUNT_ROOT redirects the interpreter's load paths to match the driver's mount (spec 17 §1; the driver gates the override on the env image's mount_root_override grant — layout schema_minor 1). The tebako-mount-root manifest derivation is untouched: the patch block still carries exactly one quoted root literal, proven by applying both variants (3.3.12 tree) — msys derives A:/t, posix /__tfs__. tools/lint green on 3.1.7/3.2.11/3.3.12/3.4.10/4.0.6 (29-30 patches each); both patched mkconfig.rb variants are ruby -c clean.

Owner-final windows root
A:/t(reverts the #49 uniformity pass) plus the run-time mount-root override: rbconfig emitsENV["TEBAKO_MOUNT_ROOT"] || '<baked>'for prefix/RUBY_EXEC_PREFIX on both variants of all 5 series. Proof: tools/lint green on 3.1.7/3.2.11/3.3.12/3.4.10/4.0.6; both patched mkconfig.rb variants ruby -c clean; the tebako-mount-root derivation still extracts exactly one root (A:/t msys, /tfs posix). Rolls as v0.2.17.
