Review of 76cd7c2. The ACL finding is right and the fix is correct — verified here that `setfacl -R -P -b`
removes the default entries as well as the access ones, which the man page splits between -b and -k and
does not settle. `acl` is already a core package in setup.sh, so the new hard dependency is real.
But the checker it added cannot fail in the way it is documented to be run.
`assert-uid-free.sh` is invoked as `sudo ./assert-uid-free.sh --check ...`, and sudo's env_reset DROPS
DATA_PATH, so the script falls back to the hardcoded `/home/pastilhas/officerdev/data` — which is not this
machine's data directory and does not exist. Every check in the file is "look for X, report ok when nothing
is found", so a missing root reports clean without looking. Demonstrated: a tree carrying both
`user:65534:rwx` and `default:user:65534:rwx` was reported as `ok no ACL entries naming uid 65534`.
The ACL check is the one that fails silently and completely, because it is the only one scoped to DATA_PATH
alone — the uid and subuid scans still walk /home and would catch something. So the check just added to
catch the hazard ownership cannot see is the check a wrong DATA_PATH disables.
Fixed by refusing rather than passing:
require_roots every search root must exist, or exit 2 naming it and showing the sudo invocation
that preserves DATA_PATH
numeric guard uid/start/count must be numbers. deprovisionOsAccount logs '<no-subuid-range>' in
that position for an account with no /etc/subuid entry, and pasting that log line in
— which is exactly how it is meant to be used — made sub_end empty and turned the
range scan into a no-op.
The handler's audit line now prints DATA_PATH inside the command it tells the operator to copy, and says
so explicitly when there is no subuid range rather than emitting a command that cannot work.
Verified: bogus root exits 2, non-numeric range exits 2, and the ACL check FAILS on a specimen tree
carrying the entries — the "make it fail before trusting it to pass" step from the spec's own subuid
section, now done for the ACL half too.
