Package: udev
Version: 1:252.6-1mx23+1
Severity: normal
X-Debbugs-Cc: frederic.lamo...@gmail.com
Dear Maintainer,
Using MX23 (Debian bookworm based), having a LUKS partition formatted with
btrfs.
When booting without systemd, some applications that query disks via
lsblk/libudev do not work
because the report is missing info about FS type and UUID.
It can be seen using command "udevadm info /dev/dm-0"
Booting with systemd, command reports:
P: /devices/virtual/block/dm-0
M: dm-0
R: 0
U: block
T: disk
D: b 253:0
N: dm-0
L: 0
