Clearly, because it's a seriously inept volume LABEL selection. Among the
following are some better, yet easy enough to remember and type, examples:
# egrep -i 'deb11|deb 11|seye|bull|debian11|debian 11' *L*txt | grep ├─ | wc -l
26
# egrep -i 'deb11|deb 11|seye|bull|debian11|debian 11' *L*txt | grep ├─
a-865L10.txt:├─sda28 ext4 SS25deb11 cb7dac29-…
ab250L26.txt:├─nvme0n1p14 ext4 pt3p14deb11 889fea98-…
The *L*txt files are automatically generated partitioner[1] logs with
both both parted -l and lsblk -f output appended, which I use for keeping
track of what's installed where here. Strings like pt3, tm8, m25 & sbyd
above are extractions from disk model and/or serial numbers.
