redbear-greeter-compositor: line 35 was using 'done < <(cmd)' bash process substitution which creates /dev/fd/63. Redox kernel does not implement /dev/fd, causing 'No such file or directory' error and compositor startup failure. Replaced 'while read; do ...; done < <(parse_drm_devices)' with 'for device in ; do ...; done' — pure POSIX, no /dev/fd dependency. Device names contain no whitespace so word splitting is correct for this use case.
