Conversation
Enhancement: Split the mount tasks so that EL7 managed nodes use the bare "mount" module (shipped as a builtin by ansible 2.9, which cannot install the ansible.posix collection) and all other systems use the fully-qualified ansible.posix.mount module. Relax the ansible.posix collection-requirements entry to drop the version cap. Reason: EL7 support requires running against ansible 2.9, where ansible.posix cannot be installed but "mount" is available as a builtin. Non-EL7 systems should use the latest ansible.posix.mount. Result: The role runs on EL7 managed nodes without the ansible.posix collection while using ansible.posix.mount everywhere else.

An unresolvable FQCN aborts play parsing on EL7 (ansible 2.9, where ansible.posix cannot be installed) even when the task is skipped by "when". The mount short name is an ansible 2.9 builtin and redirects to ansible.posix.mount on newer systems, so the EL7 and non-EL7 variants were identical apart from their gate. Collapse each mount pair into a single bare-name task (with "# noqa fqcn") that works on all platforms. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The bare mount module is needed wherever ansible.posix cannot be installed, which is any ansible 2.9 (ansible-engine) host - not EL7 specifically (EL8 with ansible-engine-2.9 hits the same constraint). Reword the comments accordingly; no behavior change. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

On ansible 2.9 (ansible-engine) the ansible.posix collection cannot be installed, and relying on the builtin mount being bundled is fragile. Vendor a dependency-free copy as mount_ansible_29 (with ismount inlined) and use it on ansible 2.9, while newer systems continue to use the bare mount name that redirects to the latest ansible.posix.mount.

20-147: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winVendored upstream copy: record the source revision.
This file is a copy of
ansible.posix.mount. The header asks maintainers to keep it in sync, but it does not name the upstream version or commit. Without that reference, a later sync cannot tell which upstream changes are already applied.Add the upstream collection version or commit hash to the header comment.
The CodeQL findings on this file (unclosed file handles at lines 270, 319, 418, 689; the redundant
msgassignment at line 613; the emptyexceptblocks at lines 1019 and 1025; the unuseddashvariables) all come from upstream code. Fixing them creates drift from upstream. Prefer dismissing them as vendored code, or suppressing them for this path in the CodeQL config.Also applies to: 224-260, 685-754

Fix the flake8 errors that fail the CI job.
The Python unit test job fails on this file. Two errors are trivial to fix:
- Line 272:
lis an ambiguous variable name (E741). - Line 895:
eis assigned but never used (F841).
The job also reports 16 W504 violations (line break after a binary operator) at lines 341-342, 375-377, 431, 462-464, 483-484, 674-675, 723, 761, and 980. That style comes from upstream ansible.posix.mount. Because you want to keep this file in sync with upstream, prefer excluding the vendored file from flake8 in the project config over reformatting the whole file. Run tox -e black,flake8 after the change.
🔧 Proposed fixes for E741 and F841

Use a Python 2-compatible exception handler.
library/mount_ansible_29.py targets Ansible 2.9 and supports EL7, where managed nodes can use Python 2.7. Python 2.7 does not define PermissionError. When open(args['fstab'], 'a') fails, evaluating that clause raises NameError instead of calling fail_json. Remove the specific clause or catch IOError/OSError and check errno.
