/etc/group - group on last line not usable? Is it a bug?

  • 772
$ cat -net /etc/group  | tail -n 3
    67  vboxusers:x:127:hannu$
    68  nvidia-persistenced:x:128:$
    69  $
$

a) With the lines as shown I get the profiling (System Settings > Color > Calibrate) for the MAIN DISPLAY ONLY (I have four of them! i.e. not full functionality) loaded as I log in. The group on line 68 is vital for xorg-edgers nvidia driver (nvidia-337 and nvidia-settings installed)

b) if I swap lines 67 and 68 I WILL NOT get to access USB devices in Virtualbox 4.3 (.12 has a remedied "Shared cliboard" compared to 4.3.10 - which is availble in U.S.C. - I have tried both).

From this I conclude that the LAST line in the /etc/groups file isn't read / used as it should. The empty line (#69) doesn't matter as it seems to me.

COMMENTS?

$ cat -net /etc/group  | tail -n 4
    67  vboxusers:x:127:hannu$
    68  nvidia-persistenced:x:128:$
    69  $
    70  DUMMY:x:65535:$

    This is my makeshift solution, need to check if this works.
