Hi, Alexander:
There will be more needed to modify for by-name support in vold.
vold uses partition number to indicate the certain partition that we
want to mount as you can see the format in vold.fstab. and vold uses
a an partition array for maintaining the partitions. You can see the
array mPartMinors in DirectVolume.cpp.
So adding "by-name" support in vold looks like not easy task and
giving the limit to vold.
