device-table.pl [-d DIR] [-f FILE]

device-table.pl -?|-h|--help|--version
|
|
|
|
=head1 Options
|
|
|
|
By default, device-table.pl writes out the device nodes in the current
|
|
working directory. Use the directory option to write out elsewhere.
|
|
|
|
multistrap contains a default device-table file, use the file option
|
|
to override the default /usr/share/multistrap/device-table.txt
|
|
|
|
Use the dry-run option to see the commands that would be run.
|
|
|
|
Device nodes needs fakeroot or another way to use root access. If
|
|
device-table.pl is already being run under fakeroot or equivalent,
|
|
use the no-fakeroot option to drop the internal fakeroot usage.
