The following features are added to the tools / library:
ebgparted.c:
Enhance block device scan algorithm:
* If the user manually changes the naming scheme of loopback devices,
detection of partitions breaks. The following gives an example case:
# Create a device node /dev/hdq equivalent to /dev/loop8
mknod /dev/hdq b 7 8
# Setup a loopback device with /home/user/testdisk.img
losetup /dev/hdq /home/user/testdisk.img
Some systems automatically create a /dev/loop8 device, others don't.
On systems, where /dev/loop8 is missing, ebgpart.c probes the file
/sys/block/loop8
and assumes, the file /dev/loop8 with the same basename exists, which
will fail.
The new algorithm also reads /sys/block/loop8/dev, which contains the
major and minor revision of the node and then looks inside /dev for
a matching node, no matter what its name is.
*Note*: It is not recommended to manually change the naming scheme,
since other tools also get into problems, for example 'lsblk', which
will not correctly print partitions.
bg_printenv:
Add the -v option according to bg_setenv to get info/debug messages
from the underlying libs.
