Otherwise 117.Fl l 118is assumed. 119.It Fl 9 120Ignore the special Win'95 directory entries even 121if deleting or renaming a file. This forces 122.Fl s . 123.It Fl G 124This option causes the filesystem to be interpreted as an Atari-Gemdos 125filesystem. The differences to the msdos filesystem are minimal and 126limited to the boot block. This option enforces 127.Fl s . 128.El 129.Sh SEE ALSO 130.Xr mount 2 , 131.Xr unmount 2 , 132.Xr fstab 5 , 133.Xr mount 8 134.Sh CAVEATS 135The use of the 136.Fl 9 137flag could result in damaged filesystems, 138albeit the damage is in part taken care of by 139procedures similar to the ones used in Win'95. 140.Pp 141The default handling for 142.Fl s 143and 144.Fl l 145will result in empty filesystems to be populated 146with short filenames only. To generate long filenames 147on empty DOS filesystems use 148.Fl l . 149.Sh HISTORY 150The 151.Nm 152utility first appeared in NetBSD 0.9. 153Its predecessor, the 154.Nm mount_pcfs 155utility appeared in NetBSD 0.8, and was abandoned in favor 156of the more aptly-named 157.Nm "" . 158
