data partition not found, missing device specific name

[Patrick Seemann]

This affects the Samsung Galaxy Tab 10.1 Wifi, device name is "p4wifi".

The "scripts/touch" script doesn't find the data partition on my device , because its name is not included in the "partlist".

The name of the userdata partition is "UA":

# find /dev -name UA
/dev/disk/by-name/UA

The name is also missing in "/usr/lib/lxc-android-config/update-fstab" from the datalabels variable. Should I file a separate bug for this ?

what is the name for the system partition, this is also needed (in a different place)

[Marcel Partap (empee584)]

As the i927's data partition also is called UA, most probably the other partition names do match as well...Please confirm this Patrick:
ES: /efs
AP: /system
CC: /cache
IS: /emmc
UA: /data
SS: /recovery
LX: /boot

system is also called "AP".

As far as matching i927's partition names goes, not all of them match:

# ls -l /dev/disk/by-name/
lrwxrwxrwx 1 15 MC -> ../../mmcblk0p6
lrwxrwxrwx 1 15 LX -> ../../mmcblk0p3
lrwxrwxrwx 1 15 MM -> ../../mmcblk0p7
lrwxrwxrwx 1 15 ES -> ../../mmcblk0p1
lrwxrwxrwx 1 15 OA -> ../../mmcblk0p9
lrwxrwxrwx 1 15 CC -> ../../mmcblk0p5
lrwxrwxrwx 1 15 SS -> ../../mmcblk0p2
lrwxrwxrwx 1 15 AP -> ../../mmcblk0p4
lrwxrwxrwx 1 15 UA -> ../../mmcblk0p8

MC: ?
LX: /boot
ES: /efs
OA: ?
CC: /cache
SS: /recovery
AP: /system
UA: /data

please add the system/data partition names to the scripts and generate a ubuntu-touch-generic-initrd 0.58 ...

[Marcel Partap (empee584)]

> mountroot()
> {
> # list of possible userdata partition names
> - partlist="userdata UDA DATAFS USERDATA"
> + partlist="userdata UDA DATAFS USERDATA UA"

is this really such a big deal?
