I'm switching to Dracut and I've numerous problems. In order to eliminate them one by one, first I want my system to boot correctly. So my Grub2 entry looks like this:

menuentry 'dracut' {

        load_video

        insmod gzio

        if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi

        insmod part_msdos

        insmod ext2

        set root='hd1,msdos1'

        if [ x$feature_platform_search_hint = xy ]; then

          search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1  829c0201-9b6d-4e18-8464-9d2551311ea6

        else

          search --no-floppy --fs-uuid --set=root 829c0201-9b6d-4e18-8464-9d2551311ea6

        fi

        echo    'Loading Linux 4.9.0-2-amd64 ...'

    linux   /vmlinuz-4.9.0-2-amd64 rd.shell rd.debug log_buf_len=1M

        echo    'Loading dracut initial ramdisk ...'

        initrd  /initramfs-4.9.0-2-amd64.img

}

I expect to be dropped into the rescue shell and then manually assemble the root file system, and continue booting; but there is no cryptsetup binary in the rescue shell.

Dracut configuration file /etc/dracut.conf.d/* looks like this:

do_prelink=no

add_dracutmodule+="cryptsetup" 

Relevant list of modules are as follows:

# dracut --list-modules | grep crypt

dracut: Executing: /usr/bin/dracut --list-modules

crypt

crypt-gpg

crypt-loop

ecryptfs

How can I add cryptsetup so I could manually unlock the encrypted partition manually (via rescue shell)?

as of debian dracut-core 044+243-3, /usr/lib/dracut/modules.d/90crypt/module-setup.sh:

require_any_binary $systemdutildir/systemd-cryptsetup cryptsetup || return 1

so dracut first tries to include /lib/systemd/systemd-cryptsetup, if the first not exist then include /sbin/cryptsetup, if neither then fail.

these are each provided by cryptsetup-bin 2:2.1.0-5 and systemd 241-1, respectively.

the usage of /lib/systemd/systemd-cryptsetup is not very same as /sbin/cryptsetup. indeed, it has less functionality:

systemd-cryptsetup attach VOLUME SOURCEDEVICE [PASSWORD] [OPTIONS]

systemd-cryptsetup detach VOLUME



Attaches or detaches an encrypted block device.



See the systemd-cryptsetup@.service(8) man page for details.

so we may want include /sbin/cryptsetup by

dracut --install "/sbin/cryptsetup" /bin/initrd.1 4.19.0-5-amd64

or in /etc/dracut.conf.d/XXX

install_items+="/sbin/cryptsetup"

finally, verify the inclusion (maybe with |grep cryptsetup):

lsinitrd /boot/initrd.1
