Thx Nick. There is not much I can find when stranded in busybox:
ls -l /sys/block/dm-*
ls: /sys/block/dm-*: No such file or directory
cd /sys/block
ls
loop3 loop5 loop7 loop0 loop2 loop4 loop6 loop1
Also running:
udevadm control --reload && udevadm trigger
doesn't change the situation, not in /sys/block, nor in /dev/disk.
I've noticed quite some changes in the systemd version of plucky (changelog),
but also that there is an updated version in -proposed - that I should probably
give a try.
On top there are several differences between 55-dm.rules and
60-persistent-storage-dm.rules between 24.04.2 and 25.04 (I should still
compare with newer 24.10 instead of 24.04.2).
And the rules are there (in initramfs):
ls
50-firmware.rules 64-btrfs.rules
50-udev-default.rules 64-md-raid-assembly.rules
55-dm.rules 69-bcache.rules
55-scsi-sg3_id.rules 69-lvm.rules
56-lvm.rules 71-seat.rules
58-scsi-sg3_symlink.rules 73-special-net-names.rules
60-block.rules 75-net-description.rules
60-persistent-storage-dm.rules 80-drivers.rules
60-persistent-storage.rules 80-net-setup-link.rules
61-persistent-storage-android.rules 81-dpm.rules
63-md-raid-arrays.rules 95-dm-notify.rules
64-btrfs-dm.rules s1lp15vg-s1lp15lv.rules
(initramfs) [6n
Incl. this one from the installation (curtin):
cat s1lp15vg-s1lp15lv.rules
# Written by curtin
SUBSYSTEM=="block", ACTION=="add|change", ENV{DM_NAME}=="s1lp15vg-s1lp15lv",
SYMLINK+="disk/by-dname/s1lp15vg-s1lp15lv"
