mkfs bug

[Jeff Nieusma]

Does anyone have any idea why SunOS 4.1 mkfs does a chgrp 3 /dev/rsd??
when you newfs a filesystem?  Sun ships /etc/group with

    bin:*:3:
    operator:*:5:

This just doesn't seem productive.  If sun wanted to assume something,
doesn't it make more sense to assume group operator ???  Has anyone else
run into this "feature" ?

    - computer% sudo chgrp operator /dev/rsd1a
    - computer% ls -lag /dev/rsd1a
    crw-r-----  1 root     operator  17,   8 Oct  9 09:17 /dev/rsd1a

    - computer% sudo newfs /dev/rsd1a
    [ ... output removed ... ]

    - computer% ls -lag /dev/rsd1a
    crw-r-----  1 root     bin       17,   8 Oct  9 09:21 /dev/rsd1a
