Hmm, at least not on two Debian systems (stretch and bullseye), I have running here: # cat /etc/debian_version 9.13 # useradd -c Foo foo # id foo uid=1021(foo) gid=1021(foo) groups=1021(foo) # cat /etc/debian_version 11.2 # useradd -c Foo foo # id foo uid=1020(foo) gid=1020(foo) groups=1020(foo) Steve
