what is group id 999?

[galen]

I've noticed several folders and files with group ID 999.
I believe those root system files and folders should be root.root not root.999

I thought I answered this.... At least I did some checking. gid from 100 to 999 are for the system (and thus root)
I did not find much more
Which files and folders did you find?

[galen]

lrwxrwxrwx 1 root 999 11 2008-10-18 18:32 cdrom -> media/cdrom
lrwxrwxrwx 1 root 999 33 2008-10-18 15:49 initrd.img -> boot/initrd.img-2.6.24-19-generic
lrwxrwxrwx 1 root 999 30 2008-10-18 15:49 vmlinuz -> boot/vmlinuz-2.6.24-19-generic

everything in /boot/grub

/etc/X11/xorg.conf

lrwxrwxrwx 1 root 999 6 2008-10-18 18:32 cdrom -> cdrom0
drwxr-xr-x 2 root 999 48 2008-10-18 18:32 cdrom0
lrwxrwxrwx 1 root 999 7 2008-10-18 18:32 floppy -> floppy0
drwxr-xr-x 2 root 999 48 2008-10-18 18:32 floppy0

and others I have yet to list

everything in /boot/grub

Confirmed
Seems that different parts of root get different gid....
Unless it is a problem for you I suggest we leave it for now and research the subject time given (and I'm on overtime )
