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.
