fbtab - change device protection upon login
The fbtab file contains lines which specify how the permissions and own-
ership of various system files should be changed based on the user's lo-
gin device name.
Comments start with a '#' and extend to the end of the line. Blank lines
or lines with only a comment are ignored.
All other lines consist of three fields delimited by whitespace.
Login Device The device you have logged in on (e.g.,
"/dev/ttyv0").
File Permission An octal permission number (0600), as used by
chmod(2).
Other devices The final field is a colon (':') delimited list of
devices (e.g., "/dev/console:/dev/fd0a"). All dev-
ice names are absolute paths. A path that ends in
"/*" refers to all directory entries except "." and
"..".
The fbtab file is used by login(1) to chown(2) the specified files to the
user who has performed a login. Additionally, chmod(2) is used to set the
devices to the specified permission. When a user logs out, init(8) is
responsible for performing the inverse operation, which results in the
files once again belonging to root.
