Re: reinstalling debian trixie with an existing encrypted setup

[Nick Gawronski <nick@nickgawronski.com>]

Hi, I think this would be a great idea as I can see lots of uses for 
reusing such a setup and not just for reinstallation but if you had 
groups like one for the root partition and one for the home partition.  
If you currently try to split your system into two volume groups with an 
one terabyte volume it does not split them evenly and I had like a ten 
megabyte group for the root and a ten megabyte for the home group.  I 
would have also thought that there would be a way to resize things like 
if you want a smaller or larger sized swap group or none at all this 
should be doable as currently once you say yes and it partitions it for 
LVM there are no ways to currently set sizes.  I do know how to pull the 
debian-installer sources from git but how do you work on the different 
items in the source tree as from reading the output of the make commands 
it looks like lots of the different components are pulled in during the 
building process already compiled so what am I missing to be able to 
look at the source code for the different components so I can do test 
builds?  One thing I was wanting to test out as I am totally blind and 
use the speech output during the installer is to build an iso image that 
just automatically boots and starts the speech output or has like a 
single letter target for running it with speech which it currently does 
with s but if you are wanting to do things like rescue mode you have to 
press < to get back to the main menu then load the rescue mode guessing 
at when is the proper time after having debconf set to low priority and 
then you might not find the numbered choice in the menu in time after 
some steps are properly picked.  Nick Gawronski
