Device Table⚓︎
When building a target filesystem, it is desirable to not have to
become root and then run 'mknod' a thousand times. Using a device
table you can create device nodes and directories "on the fly".
This is a sample device table file for use with genext2fs. You can
do all sorts of interesting things with a device table file. For
example, if you want to adjust the permissions on a particular file
you can just add an entry like:
root (regardless of what its permissions are on the host filesystem.
Furthermore, you can use a single table entry to create a many device
minors. For example, if I wanted to create /dev/hda and /dev/hda[0-15]
I could just use the following two table entries:
Device table entries take the form of:
f A regular file
d Directory
c Character special device file
b Block special device file
p Fifo (named pipe)
target file. The rest of the entries (major, minor, etc) apply only
to device special files.
