Hi Scott 1, why on cenga, download folder for all layer is blank now. http://mirror.starlingx.cengn.ca/mirror/starlingx/master/centos/flock/latest... http://mirror.starlingx.cengn.ca/mirror/starlingx/master/centos/distro/lates... http://mirror.starlingx.cengn.ca/mirror/starlingx/master/centos/containers/l... http://mirror.starlingx.cengn.ca/mirror/starlingx/master/centos/compiler/lat... 2, the latest_build saved binary, is now target for monolithic build. Correct? http://mirror.starlingx.cengn.ca/mirror/starlingx/master/centos/latest_build... Or now should only use mirror for layer builder http://mirror.starlingx.cengn.ca/mirror/starlingx/master/centos/<layer>/ Thanks! Martin, Chen IOTG, Software Engineer 021-61164330
