[SOLVED] scencrypt: "/init: line 212: can't create /tmp/cmdline"

cassowarry · 2024-06-19 15:36:24

Hello all!

since about a month I get the the following error messages on boot:

/init: line 212: can't create /tmp/cmdline: nonexistent directory
/init: line 212: can't create /tmp/cmdline: nonexistent directory
/init: line 212: can't create /tmp/cmdline: nonexistent directory
/init: line 212: can't create /tmp/cmdline: nonexistent directory
/init: line 212: can't create /tmp/cmdline: nonexistent directory

Starting systemd-udev version <version of systemd>
:: running hook [udev]
:: Triggering uevents...
:: running hook [keymap]
:: Loading keymap...done.

I have never had this before. Before the only boot messages were:

Starting systemd-udev version <version of systemd>

I'm running Arch on a ASUS G14 with LUKS full disk encryption (except /efi), Secure Boot, Unified kernel image and BTRFS. My fstab is as follows:

UUID=9201f887-1f6d-4870-b785-95aceaa17487	/		btrfs	defaults,noatime,nodiratime,compress=zstd:3,ssd,discard,space_cache,subvolid=256,subvol=root	0 0

Does anyone have an idea what has changed?

It would seem that the /init in the initramfs isn't systemd but some script?
You could extract it and inspect the file - might hint where it's coming from.

cassowarry · 2024-06-20 14:03:15

It is a regular Arch install with systemd. It worked without the error message since installing Arch two years ago. But since an system update a month or two ago the error messages show up. It looks like the problem lies in init_functions of the standard mkinitcpio and came with commit 56228734a16bc69eaca7bc2c9feb91eb2d7206dd. I tried to open a ticket but I can't get an account because account creation is temporarily disabled.

Sanity check:

 sudo lsinitcpio /boot/initramfs-linux*.img | grep tmp

cassowarry · 2024-06-20 15:10:27

$ sudo lsinitcpio /boot/initramfs-linux-zen.img | grep tmp
usr/bin/systemd-tmpfiles

seth · 2024-06-20 15:17:40

Explains the error but why's there no tmp/ dir?
mkinitcpio.conf and what's the output of "mkinitcpio -P"?

cassowarry · 2024-06-20 15:44:06

mkinitcpio.conf:

# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES=(usbhid xhci_hcd)
MODULES=(btrfs amdgpu)

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=()

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.
FILES=()

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No RAID, lvm2, or encrypted root is needed.
#    HOOKS=(base)
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS=(base udev autodetect modconf block filesystems fsck)
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS=(base udev modconf block filesystems fsck)
#
##   This setup assembles a mdadm array with an encrypted root file system.
##   Note: See 'mkinitcpio -H mdadm_udev' for more information on RAID devices.
#    HOOKS=(base udev modconf keyboard keymap consolefont block mdadm_udev encrypt filesystems fsck)
#
##   This setup loads an lvm2 volume group.
#    HOOKS=(base udev modconf block lvm2 filesystems fsck)
#
##   This will create a systemd based initramfs which loads an encrypted root filesystem.
#    HOOKS=(base systemd autodetect modconf kms keyboard sd-vconsole sd-encrypt block filesystems fsck)
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr and fsck hooks.
HOOKS=(base udev autodetect microcode block kms keyboard keymap scencrypt fsck)

# COMPRESSION
# Use this to compress the initramfs image. By default, zstd compression
# is used for Linux ≥ 5.9 and gzip compression is used for Linux < 5.9.
# Use 'cat' to create an uncompressed image.
#COMPRESSION="zstd"
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"

# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=()

# MODULES_DECOMPRESS
# Decompress loadable kernel modules and their firmware during initramfs
# creation. Switch (yes/no).
# Enable to allow further decreasing image size when using high compression
# (e.g. xz -9e or zstd --long --ultra -22) at the expense of increased RAM usage
# at early boot.
# Note that any compressed files will be placed in the uncompressed early CPIO
# to avoid double compression.
#MODULES_DECOMPRESS="no"

initramfs still has not tmp/ dir?
The only things that stick out are the yubikey scencrypt hook and the "drop-in configuration file: 'asus.conf'" - what is the latter and does removing that and scencrypt add a tmp/ dir?

What if you explicitly add "FILES=(/tmp/foo)" to the mkinitcpio.conf and

echo bar > /tmp/foo

before you generate it?
Do you get tmp/ and tmp/foo?

cassowarry · 2024-06-21 22:43:26

Thank you @seth for your help. asus.conf is supplied from asus-linux and is fairly simple:

MODULES+=(hid_asus asus_wmi asus_nb_wmi)

I removed it and still no tmp/ dir.

cassowarry · 2024-06-21 22:50:24

I removed the hook scencrypt and the directory tmp/ was in the initramfs. I think you found the culprit. Thank you. Now I need to figure out what needs to be changed to have scencrypt and tmp/.

Thank you @seth for pointing this out. It solved the problem.

You probably want to file a bug for this at https://github.com/fuhry/initramfs-scencrypt/issues
