37 .Nd label conversion file for device paths
41 file contains label conversions for
45 and other commands which expect device paths.
46 It is typically used to translate longer serial numbers (which
48 automatically creates as
49 .Pa /dev/serno/<serial>[.suffix] )
50 into short form names.
53 is only read by programs, and not written;
54 it is the duty of the system administrator to properly create
55 and maintain this file.
56 Each conversion is described on a separate line;
57 fields on each line are separated by tabs or spaces.
59 The first field specifies the conversion's label.
61 The second field is the conversion's type.
63 .Bl -tag -width ".Sy serno" -offset indent
68 Translates to the path as specified
71 The third field specifies the conversion's base path
73 .Bl -tag -width ".Pa /etc/devtab" -compact
81 This will translate references like
85 .Pa /dev/serno/L123456
88 .Dl "fubar serno L123456"
90 This will translate references like
97 .Dl "fubar path /full/path"
