 |
|
Want to have an encryped swap partition.
| Code: | config.toml:
# This config will decrypt the LUKS volume with uuid "fdf442da-0574-4531-98c7-55227a041f1d", mapping it to "/dev/mapper/root"
# It will attempt to mount the btrfs volume with label "rootfs" to /target_rootfs
# It will pull all current kernel modules from lspci -k results
# It will try to process the cmdline and mount the rootfs based on the root= parameter
modules = [
"ugrd.crypto.cryptsetup", # This is included by the gpg module
"ugrd.base.debug",
"ugrd.fs.resume" ,
"ugrd.fs.mdraid" ,
]
binaries = ['cat', 'dd', 'lsmod', 'udevadm', 'mdadm', 'cp', 'killall', 'ls', 'mkdir', 'mknod', 'mount', 'umount', 'sed', 'sleep', 'ln', 'rm', 'uname', 'readlink', 'basename', 'modprobe', 'readlink', 'basename', 'mdmon', 'udevd', 'cryptsetup']
kmod_autodetect_lspci = true
kmod_init = ["usbhid", "hid_logitech_hidpp", "hid_logitech_dj", "hid_generic", "raid0", "raid1", "raid10", "raid456"]
# If the root is a LUKS volume, specify the LUKS volume information
[cryptsetup.root]
# The UUID of the encrypted volume, mounted at /dev/mapper/root
uuid = "2152888b-67cb-4339-a2f4-680bf955c46b"
key_file = "/etc/cryptsetup-keys.d/gentoo.key"
dependencies = [ "/etc/cryptsetup-keys.d/gentoo.key" ]
# If the root is a LUKS volume, specify the LUKS volume information
[cryptsetup.swap]
# The UUID of the encrypted volume, mounted at /dev/mapper/root
uuid = "86f67200-c891-47d3-bdd4-f8e58322325d"
key_file = "/etc/cryptsetup-keys.d/gentoo.key"
dependencies = [ "/etc/cryptsetup-keys.d/gentoo.key" ] |
ugrd fails with: | Code: | | CRITICAL | No device mapper information found for: root |

stripped blkid:
| Code: | /dev/md125p7: UUID="2152888b-67cb-4339-a2f4-680bf955c46b" TYPE="crypto_LUKS" PARTUUID="3f8de685-9ea2-9d40-abea-97d2c736c8c6"

*********************************
With confif;toml:
| Code: | # This config will decrypt the LUKS volume with uuid "fdf442da-0574-4531-98c7-55227a041f1d", mapping it to "/dev/mapper/root"

modules = [
"ugrd.crypto.cryptsetup", # This is included by the gpg module
"ugrd.base.debug",
"ugrd.fs.resume" ,
"ugrd.fs.mdraid" ,
]
binaries = ['cat', 'dd', 'lsmod', 'udevadm', 'mdadm', 'cp', 'killall', 'ls', 'mkdir', 'mknod', 'mount', 'umount', 'sed', 'sleep', 'ln', 'rm', 'uname', 'readlink', 'basename', 'modprobe', 'readlink', 'basename', 'mdmon', 'udevd', 'cryptsetup']
kmod_autodetect_lspci = true
kmod_init = ["usbhid", "hid_logitech_hidpp", "hid_logitech_dj", "hid_generic", "raid0", "raid1", "raid10", "raid456"] |
ugrd gives no error:
During boot grub asks for parphrase which is normal.
also for root:
want to use a key-file.
later when gentoo boots kernel swap is not found and waits 1.5 min.
System boot futher and is ok.
********
during starting with initramfs in debug-mode.
| Code: | | cryptsetup open /dev/sdg1 swap is done |
system starts normal
and top shows the swap is present
Is more information needed?
Thanks
