By default, \fIdevice\-table.pl\fR writes out the device nodes in the current
working directory. Use the directory option to write out elsewhere.
.PP
multistrap contains a default device-table file, use the file option
to override the default \fI/usr/share/doc/multistrap/examples/device_table.txt\fR
.PP
Use the dry-run option to see the commands that would be run.
.PP
Device nodes need fakeroot or another way to use root access. If
\&\fIdevice\-table.pl\fR is already being run under fakeroot or equivalent,
the existing fakeroot session will be used, alternatively,
use the no-fakeroot option to drop the internal fakeroot usage.
.PP
Note that fakeroot does not support changing the actual ownerships,
for that, run the final packing into a tarball under fakeroot as well,
or use \f(CW\*(C`sudo\*(C'\fR when running \fIdevice\-table.pl\fR
.SH "Device table format"
.IX Header "Device table format"
Device table files are tab separated value files (\s-1TSV\s0). All lines in the
device table must have exactly 10 entries, each separated by a single
tab, except comments \- which must start with #
.PP
Device table entries take the form of:
.PP
.Vb 1
\& <name> <type> <mode> <uid> <gid> <major> <minor> <start> <inc> <count>
.Ve
.PP
where name is the file name, type can be one of:
.PP
.Vb 7
\& f A regular file
\& d Directory
\& s symlink
\& h hardlink
\& c Character special device file
\& b Block special device file
\& p Fifo (named pipe)
.Ve
.PP
symlinks and hardlinks are extensions to the device table, just for
\&\fIdevice\-table.pl\fR, other device table parsers might not handle these
types. The first field of the symlink command is the existing target of
the symlink, the third field is the full path of the symlink itself.
e.g.
.PP
.Vb 1
\& /proc/self/fd/0 s /dev/stdin \- \- \- \- \- \- \-
.Ve
.PP
