Dear Maintainer,

I have noticed this for some time while installing Debian 13, Recently I have noticed an uptick in people wanting to migrate away from windows. Something I encourage. During installation I generally advise people to use automatic partitioning using lvm with encryption. The issue is with the defailt size allocation for the / partition when asking for separate /home or separate /home, /tmp and /var partitions. On a 1 terrabyte disk it allocates 30 GB for root. This is very small for a desktop. It would be helpful to either have a distinction before selecting a disk, ie "server" and "desktop" or the posibility to change the default distrubtion between the different volumes in the vg. This could help in furthering adaptation of Debian, I have used Debian for more then 26 years now. That's the reason I advise it to others.
Kind regards,

Lodi de Charro

AFAICS on a 1TB disk the space allocated to the root partition/volume is
about 60GB (~5%), not 30.

IME even 30GB is more than enough in many desktop use cases. My own root
filesystem (including /var) uses less than 10GB. However on smaller disk
sizes such as 250GB, it has been reported that the root filesystem may
be too small in some use cases, so one may consider raising the root
filesystem priority in partman-auto "home" and "multi" recipes a bit.
recipe, which allocates most disk space to /srv instead of /home. But
the space allocated to / is about the same as in "home" and "multi".

Guided partitioning with LVM gives the option to reserve some free space
in the VG for future allocation. You can use this space to grow logical
volumes as needed.
