Finally ran the net installer in rescue mode, copied my 122gb /home dir, on a 1.9T raid10 to a different drive and reinstalled, then copied it back, but kmail refuses to use the copied back data so I'm using FF to post this.

Understandable maybe 5% of the time. I purposely did NOT even visit those pieces of the installer for fear it would be enabled, because even though killed by removing brltty in the previous install, 90% of the syslog was errors because it couldn't use brltty. But I got it anyway.  So how do it get rid of it without it tearing down the system with its copius error screaming?

I have removed brltty, and that IS the 15 second showstopper. But if my

already annoyingly high. Which with this system means at least a day to 
do it.

I recall that you have several computers, that your hobby is using Linux 
for CNC woodworking, and that you modify the OS's significantly and/or 
install specialized, non-Debian software.

I have found that when I install too much software, when I put 
non-Debian software on a Debian computer, and/or when I make too many 
changes to the OS and/or software, that the computer becomes unstable.

I have found it useful to spread storage and functionality across 
several computers, to limit the scope of disasters and to facilitate 
recovery.  These are the three key computers at my site:

1.  Primary workstation.

2.  Live server (Samba and SSH/CVS).

3.  Backup/ archive/ image/ replication server.

For Debian and FreeBSD machines, including the above, I install the OS 
as follows:

1.  Disconnect all hard disk drives, solid-state drives, USB flash 
drives, SDHC cards, etc..

2.  Disconnect all external devices from the computer except a keyboard, 
a mouse, a monitor, and the network connection (servers and desktops), 
or the network connection (laptops).

3.  Install a blank SSD.  Ensure that it is the first device node when 
the installer runs (e.g. /dev/sda).

4.  Do the simplest install of the OS of choice onto the SSD, using 
BIOS, MBR, and partitioning the OS drive such that the system image fits 
onto "16 GB" devices with room to spare -- 1 GB ext4 boot, 1 GB 
encrypted swap, 12 GB encrypted ext4 root.

For the key computers, I then install "official" packages for only the 
software needed for the chosen function.  For a Debian primary 
workstation, I also install the Debianized VirtualBox from Oracle.

I use VM's and/or additional computers for everything else.

The small OS image size makes it easy to take and restore images; 
monthly and as needed.  I keep all of the system configuration files in 
a version control system (CVS).  And, I backup boot and root daily and 
as needed.  So, when an OS instance becomes damaged, recovery is 
straight-forward.

Your computer with the RAID10 (4 @ 1 TB HDD?) would seem to be the 
logical choice for use as a live server.  Put the OS on a small SSD and 
use the big disks for data.

Pick a machine to use as your workstation.  Put the OS on a small SSD 
and move as much of the 122 GB as you can to the live server.  My home 
directory is ~2.6 GB and fits on root.  Most of that is used by Xfce and 
apps.  The only volatile user data is e-mail.  If you cannot shrink your 
home directory, move it to another partition or to a second SSD.

Pick a machine to use as your backup (Amanda?), etc., server.  Again, a 
small SSD for the OS; one or more big disks for backups, etc..
