- (Object) changeOrderInDeviceMapping(bad_devices)

This function changes order of devices in device_mapping. All devices listed in bad_devices are maped to "hdN" are moved to the end (with changed number N). And second step is putting device with boot partition on top (i.e. device_mapping = "hd0").

Example: device_mapping = $[ "/dev/sda" : "hd0", "/dev/sdb" : "hd1", "/dev/sdc" : "hd2", "/dev/sdd" : "hd3", "/dev/sde" : "hd4" ]; bad_devices = [ "/dev/sda", "/dev/sdc" ];

 changeOrderInDeviceMapping(bad_devices);
 // after call, device_mapping is:
 device_mapping -> $[ "/dev/sda" : "hd3",
                      "/dev/sdb" : "hd0",
                      "/dev/sdc" : "hd4",
                      "/dev/sdd" : "hd1",
                      "/dev/sde" : "hd2" ];

- (String) Dev2MountByDev(dev)

FATE #302219 - Use and choose persistent device names for disk devices Converts a device name to the corresponding device name it should be mounted by, according to the "mountby" setting for the device from yast2-storage. As a safeguard against problems, if the "mountby" device name does not exist in the information from yast2-storage, it will fallback to the "kernel name" ("/dev/sdXY").

Parameters:

  • dev (String)

    string device name

Returns:

  • (String)

    device name according to “mountby”

If the given device name is not a "/dev/disk/by-" device name, it is left unchanged. Also, if the information about the device name cannot be found in the target map from yast2-storage, the device name is left unchanged.

Parameters:

Generate device map proposal, store it in internal variables.

FATE #302075: When user is installing from USB media or any non IDE disk or bios simply set any non IDE disk as first and user is not installing on this removable (non IDE) disk, the order of disks proposed by bios must be changed because of future remove of USB disk. This function must find right place for bootloader (which is most probably boot sector of boot partition (where /boot dir is located)) and change the order of disks in device map. This method is only heuristic because order of disks after remove of usb disk can't be determined by any method.

Algorithm for solving problem with usb disk propsed by bios as hd0: if usbDiskDevice == hd0 && BootDevice != usbDiskDevice: change order of disks in device_mappings to have BootDevice as hd0 FIXME: remove that function from here, as it is grub only NOTE: there is a local copy in routines/grub/misc.ycp now
