Für dich und mich hier und jetzt nicht überprüfbar, ein Journalist dürfte kein Problem damit haben, den Anwalt zu kontaktieren und evtl. entsprechende Dokumente zu sichten, auch wenn die Behörden momentan die Auskunft verweigern. Die Idee, dass der Anwalt hier einfach lügt, oder dass The Intercept das falsch darstellt, ist hahnebüchen.
Can you provide output of
which sway
,sway --version
,file $(which sway)
andls -l $(which sway)
?Also, can you run
id
, after logging in w/o gdm on the console, and then again after starting sway?The fact that your group membership changes even when starting sway from a tty, as mentioned in some other comment, is super weird. I believe newer versions of sway should not mess with this.
AFAIK some versions ago, sway used to be (or at least could be) a setuid root binary (something something needed root privileges for some reason to do with h/w access), but no longer. Back then it looks like it did mess with group membership etc.
I have this hunch, that maybe your binary has the setgid bit set for some reason (due to, perhaps, an oversight made by the packager, because in the old package that was needed).
