Comment # 2 on bug 1213595 from Fabian Vogt

According to blkid, both /dev/sda and /dev/sda1 have
LABEL="openSUSE_Leap_15.5_KDE_Live" and udev links sda into /dev/disk/by-label.
This means that the whole disk is mounted, not just the first partition.

Can it be avoided that the label is also visible on /dev/sda?

Any idea what could cause this behaviour change?
At least in the current TW snapshot it appears to be working.
