Start_gui is not being called while booting #264
Description
On a Kiosk OS that I'm making I just realize that start_gui is not being called. First I thought it was matchbox-window-manager crashing on Trixie, but after all it happened the same in bookworm, then I added a simple sudo touch /etc/hi at the beginning of the start_gui and after reboot no /etc/hi file was found, so, for me, somehow start_gui is not being called (a year ago I used CustomPiOS for the same Kiosk OS and it worked fine, now I just changed some lines of code and it stopped working).
The dmseg doesn't show any error message, but lightdm.service shows the following message:

(Those errors are in yellow so it's seems the service trait them as warning rather than errors)
I've attached both the start_chroot_script (I had to upload it as .txt because of GitHub limitations) and the build.log
Edit: By the way, I'm using Bookworm as CustomPiOS has no support for Trixie yet (On Trixie I had a black screen and on Bookworm I have a terminal login prompt. On both no GUI whatsoever)

Workaround for Bookworm: I had to set the
autologin-user-timeoutto 5 seconds (maybe a lower value as 2s would also work), so I had to add this to myend_chroot_scriptThe only caveat is that the login screen (asking for the password) will appear for a moment (something near to a second or two, even if the timeout is set to 5)

Huh strange for it to be a timing issue. will have to look in to it
