[SOLVED] timestamp hook replacement by systemd hook

KairiTech · 2013-09-19 20:27:58

Synopsis: Remove timestamp hook until systemd support in initramfs has more time to mature.

Per the mkinitcpio wiki, If I swap out the timestamp hook from this...

HOOKS="base hushkernel udev autodetect block mdadm_udev keyboard keymap encrypt lvm2 filesystems timestamp shutdown"

...with the systemd hook like this...

HOOKS="base hushkernel udev autodetect block mdadm_udev keyboard keymap encrypt lvm2 filesystems systemd shutdown"

...all I get is the "Welcome to emergency mode!" message.

What am I doing wrong?

See below for my custom hushkernel hook.

/usr/lib/initcpio/hooks/hushkernel

#!/usr/bin/ash

   # The four values in printk denote: console_loglevel, default_message_loglevel, minimum_console_loglevel and default_console_loglevel respectively.
 
   # These values influence printk() behavior when printing or logging error messages. See 'man 2 syslog' for more info on the different loglevels.
 
   # • console_loglevel: messages with a higher priority than this will be printed to the console
   # • default_message_level: messages without an explicit priority will be printed with this priority
   # • minimum_console_loglevel: minimum (highest) value to which console_loglevel can be set
   # • default_console_loglevel: default value for console_loglevel
 
   #define  KERN_EMERG    "<0>"  /* system is unusable               */

   #define  KERN_DEBUG    "<7>"  /* debug-level messages             */
 
   echo "3 3 3 3" > /proc/sys/kernel/printk

/usr/lib/initcpio/install/hushkernel

#!/bin/ash
 
build() {
   add_runscript
}
 
help() {
   cat <<HELPEOF
 
This hook will suppress kernel messages during the boot LUKS password prompt

shutdown hook got removed too.

Do you get any errors / warnings when you generate the initramfs?

KairiTech · 2013-09-19 20:53:53

Nothing other than...

==> WARNING: Possibly missing firmware for module: aic94xx
==> WARNING: Possibly missing firmware for module: bfa
==> WARNING: Possibly missing firmware for module: smsmdtv

What? That's not at all what that mailing list post says. The shutdown hook hasn't gone anywhere.

OP's problem is in thinking that the systemd hook is an actual replacement for the timestamp hook. It isn't. If you want the old initrd timestamping functionality, then you need to also use systemd as your early userspace init. This has lots of caveats at the moment which are well documented.

Sorry, my mistake.
Should have checked the wiki.

I think the mdadm hook won't work with the systemd yet, so there will be more problems.

I have also removed udev and placed systemd after base. Base can also be removed in the most use cases.

OP uses mdadm_udev which 'works out of the box' with systemd.

Are you saying that I misunderstood something again?

My comment was incomplete /and inaccurate. I knew that some of the mount hooks arent't working in this setup but I wasn't sure which ones. I reread the source files again and mdadm_udev works fine, but the encrypt and lvm2 hooks don't work. Somehow I referred to all three hooks incorrectly as "mdadm". WonderWoofys link provides hooks that work with systemd in the initramfs.

No, my intent there was to try to bolster your post with links… which I was surprised that you didn't link to yourself.
