Package: initramfs-tools
Version: 0.139
Severity: important
Dear Maintainer,
I understand that separate /usr is deprecated, but many users do not
have the luxury of wiping and reinstalling their entire system. Rather,
a simple dist-upgrade procedure is expected to produce a working system,
making a best effort to migrate previously supported configurations.
Given that, upgrading a system to buster will break booting if the
following two conditions are true:
* /usr is a mount for a separate block device
* The block device containing the /usr filesystem is a LVM volume.
The reason is because the script
/usr/share/initramfs-tools/scripts/local-top/lvm2 only attempts to
activate the root and resume devices, and no other devices.
Unfortunately, systemd which has been introduced with buster introduces
a new boot dependency on /usr.
I have created the following workaround:
# DEV=$(lsblk -p -f -l | grep '\/usr' | awk '{print $1}' | sed 's/\//\\\//g');
cat /usr/share/initramfs-tools/scripts/local-top/lvm2 | sed 's/^exit
0$/activate "'${DEV}'"; exit 0/' > /etc/initramfs-tools/scripts/local-top/lvm2
This produces the following diff:
# diff -u /usr/share/initramfs-tools/scripts/local-top/lvm2

Another part of the initramfs scripts mounts a separate /usr filesystem
if the block device exists; this workaround is strictly to ensure the
LVM device is activated so that the later code can actually mount it.
