Package: udev-udeb
Version: 241-7~deb10u3
Control: found -1 232-25+deb9u12

Hello,
Udev has a rule with OPTIONS+="watch" to generate an event and update
symlinks in /dev/disk/ when a block device is written to. In Jessie, the
rule was in /lib/udev/rules.d/60-persistent-storage.rules. In Stretch
and Buster, it was moved to /lib/udev/rules.d/60-block.rules. However
/lib/udev/rules.d/60-block.rules was *not* included in :
- the initramfs hook script /usr/share/initramfs-tools/hooks/udev,
therefore in the initramfs built by update-initramfs
- the udev-udeb package
- the Debian installer initrd.gz (I guess it uses udev-udeb)
The most visible consequence is in the Debian installer. When a device
is formatted, symbolic links pointing to that device in /dev/disk/ are
not updated immediately. Then if the symlink pointing to the root device
in /dev/disk/by-uuid/ is missing or wrong, update-grub/grub-mkconfig
puts the root device name instead of the UUID in the root= kernel
parameter (see /etc/grub.d/10_linux). Drive and partition device names
are unreliable and may change at each boot, causing the boot to fail.
The following bugs may be related to this issue :
852323
863815
876866
925556
Steps to reproduce the issue :
Boot the Debian installer.
Select "advanced options" > "Expert install".
Follow steps up to "Partition disks".
Select manual partitioning.
Create or select and format a partition for /.
Do not create or use any swaps.
Install the base system.
Skip "Configure the package manager" and "Select and install software".
Install the GRUB boot loader.
Jump into a shell.
Check the symlink pointing to the root partition in /dev/disk/by-uuid/
is missing or wrong.
Check that /target/boot/grub/grub.cfg "linux" lines have
root=/dev/<partition> instead of root=UUID=<uuid>.
Suggested fix :
The issue could be worked around by executing "udevadm trigger" to
update symlinks at a proper time after formatting the root filesystem
and before installing GRUB. This is actually what seems to happen at the
"select and install software" step. But I think is is easier, safer and
cleaner to include /lib/udev/rules.d/60-block.rules and fix the root
cause than to rely on executing "udevadm trigger" at the proper time.

Changed-By: Michael Biebl <[email protected]>
Closes: 958397
Changes:
systemd (245.5-2) unstable; urgency=medium
.
* Cherry-pick various fixes from upstream master
- network: add a flag to ignore gateway provided by DHCP server
- userdb: when doing client-side NSS look-ups optionally avoid shadow
look-ups
- nss-systemd: don't synthesize root/nobody when iterating
- core: make sure we don't get confused when setting TERM for a tty fd
- core: make sure to restore the control command id, too
* Install 60-block.rules in udev-udeb and initramfs-tools.
The block device rules were split out from 60-persistent-storage.rules
into its own rules file in v220. Those rules ensure that change events
are emitted and the udev db is updated after metadata changes.
