Title:
[18.04] update-initramfs fails to generate correct initrd
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hi
I get many trouble in trying to generate a correct initrd.img for the
following configuration
clear lvm on /dev/sd4 partition (msdos)
several logical volumes, some clear and some luks-encrypted
/ et /home on encrypted logical volumes, each with its own 512 byte binary
key-file on removable device (USB stick)
/boot et /usr on clear logical volumes
I am still running 14.04 due to trouble with 16.04, maybe because I
missed the introduction of the "initramfs" crypttab option. I dropped
any investigation hoping for the trouble being solved with 18.04. This
is not the case.
I run into trouble as soon as I tried to update initrd.img with
update-initramfs.
victor-odos goes to /, victor-oikia goes to /home
I rewrote passdev and stored it in /lib/cryptsetup/bash/passdev
1/ with crypttab referencing my binary key-files
victor-odos /dev/mapper/victor-odos_l
/dev/disk/by-uuid/4146dfad-26f0-4aec-99c3-8ab00c3e4297:/.ckf/victor-odos:1
luks,keyscript=/lib/cryptsetup/bash/passdev,initramfs
victor-oikia /dev/mapper/victor-oikia_l
/dev/disk/by-uuid/4146dfad-26f0-4aec-99c3-8ab00c3e4297:/.ckf/victor-oikia:1
luks,keyscript=/lib/cryptsetup/bash/passdev,initramfs
I join two files : /dev/stdout sent to .log and /dev/stderr to .err
2/ with no key-files
victor-odos /dev/mapper/victor-odos_l none luks,initramfs
victor-oikia /dev/mapper/victor-oikia_l none luks,initramfs
I don't know how to bypass this issue
When this has been solved, I intend to detach luks headers. How to code
crypttab as I don't know the operational file hierarchy inside initrd ?
