Over the last two days I've twice done a fresh install of -current and
have noticed some changes in the procedure.
It use to be that when you told the installer to format a partition (quick, no bad block testing) it would wipe the partition. Not any more.
If you use the same fie system, in this case f2fs, it doesn't wipe the drive and installs over the previous installation. If there have been updates to a application, the updated version is installed right beside the old version. This also leaves all the other applications you have have installed and any files or configuration files you may have install, e.g., hosts, group, your firewall (if you added one), etc., etc., etc.
The only way I could get it to re-format a partition was to reformat the partition with a different file system, then go back and reformat with the desired file system.
Were these changes done on purpose?
Oh, after seeing this with the -current .iso of 27 May, I waited a day and downloaded the -current .iso for 28 May. Same problems.
