Firstwhat version of adduser?? because in my version of adduser(3.11.1)
idon't have that -m flag, now looking at the code, i didn't find it and
in the man page i didn't find it either. About the user bit, the thing
is if you have USERGROUPS=yes, and you have USER_GID=100 adduser it
apparently is defaulting to use this value, i don't know why but it
doesn't make sense the code is very sane, and in my interpretation of it
this shouldn't happen maybe a bug don't know yet *shrug*, try using the
--gid flag and see if it's fixed.

I don't know if it's an old location, but it seems it checks to see if
that file exist for some reason *shrug*. I don't see no reference to
this in the code i have.
