DBUS Nightmares (recent 'sabotage?') and rant, 2023 failing of Arch

DBUS Nightmares (recent 'sabotage?') and rant, 2023 failing of Arch

Before anyone decides to jump down my throat.

I am a 10 year daily arch user, and have used 90% of the day and night every days sans a 2 week vacation since.
I had install and maintain multiple machines for others.
I am skilled at sys admin. I have used arch for web server and local.
Linux us linux of course regardless of distribution with only minor differences, but notably maintainer, packaging and deliverance.

I have both very simple systems with maybe 2 sata drive, one for OS/linux and another for example for media. NTFS (of which on linux for 20 YEARS never ever ever ever ever ever had issue until 2023 now, tested and occuring on multiple independent machines = DBUS SABOTAGE/INCOMPTENT ERRORS.
