[14:52] <enyc> I'd like to wundersatnd (please) how/where best to look to try to track-down an installer-relahed bug.
[14:52] <enyc> Even if you "swapoff -a" and check /proc/swaps empty... when runnnig ubiquity from e.g.  18.04 MATE 64bit image,  and doing e.g.  custom-partitioning,  -- it keeps 're-swapon' existing linux-swap partitions...
[14:53] <enyc> This causes problems for editing partitions, or donig things like creating a (separate) encrypted partition (for 'encrypted install' dualboot with other older installs)  this then refuses, because  'unsafe swap detected'  error  as the swap is automounted at wrong time / automatically.
[14:53] <enyc> Should I be looking in ubiquity itself?  is there likely something triggered by 'rescan-partitions' call, e.g. in udev//systemd somewhere-else,  as part of the live-cd arrangement ?
