@fsmithred that sounds like a likely fix.

Would you mind posting an example of one of your fstab mounts - just to make sure the autofs option is the only one needed!

Thanks

thanks @Andre4freedom, good to know I'm not the only one experiencing this issue.

I guess the reason you may be seeing this with WLAN only may be that your ethernet connection is set in /etc/network/interfaces.  Interfaces defined there will no longer be managed by Network Manager.

Unmounting NFS shares manually certainly works, but I have a bad habit of forgetting this, and I'm sure it will be possible to solve with the right sysvinit script tweaks...

When I have NFS shares mounted, shutdown hangs (last message from rsyslog).

This is with Devuan Daedalus on Lenovo Thinkpad P14s (AMD edition).

I believe this is related to the order of events at shutdown (using sysvinit).

See ls /etc/rc6.d

K01alsa-utils	   K01lightdm			   K01vboxballoonctrl-service  K06umountnfs.sh
K01bluetooth	   K01openvpn			   K01vboxweb-service	       K07nfs-common
K01brightness	   K01pcscd			   K02avahi-daemon	       K07rpcbind
K01cups-browsed    K01pulseaudio-enable-autospawn  K02libvirtd		       K08hwclock.sh
K01docker	   K01saned			   K02network-manager	       K08networking
K01elogind	   K01speech-dispatcher		   K02vboxdrv		       K09umountfs
K01eudev	   K01tlp			   K03virtlogd		       K10umountroot
K01glances	   K01urandom			   K04sendsigs		       K11reboot
K01libvirt-guests  K01vboxautostart-service	   K05rsyslog		       README

I tried moving network manager to later in the shutdown sequence as I think the NFS umount is failing due to having network stopped first.

mv K02network-manager K07network-manager

That helps, now shutdown does complete, but there is a long delay if an NFS share is mounted.

I have tried changing the timeo property in the mount (from /etc/fstab):

nfserver:/data/media/video                        /mnt/media/video        nfs     defaults,soft,timeo=5,rw,_netdev        0       0

but the timeout doesn't seem to change the shutdown delay.

So 2 questions:

1. should the Devuan nfs-client package be updated to make sure nfsumount happens before network manager shutdown?
2. is there a way to control the NFS umount wait time so that the shutdown delay is not so long

p.s. just reporting back here too, Devuan runs very well on this laptop with a few little tweaks, thanks for all the great work maintainers!

#5 Re: DIY » missing sysvinit config for power-profiles-daemon » 2023-12-01 02:14:06

Thanks GlennW, a useful script!

There are a few things to consider as far as the best power management solution...

Here are some useful references:
- https://www.reddit.com/r/thinkpad/comme … ittle_fan/
- https://wiki.archlinux.org/title/Lenovo … -State_EPP
- https://www.phoronix.com/review/linux-65-thinkpad
- https://www.phoronix.com/news/Linux-6.6 … Management

Currently, I am using the 6.5.0.0. kernel from daedalus-backports.

aluma, if you are having sleep issues, you may want to try that kernel, no sleep issues for me.
However, the wifi driver doesn't wake from hibernate (known issue for that kernel driver)
- https://wiki.archlinux.org/title/Lenovo … ibernation

Note that I have tried the suggestion from the reddit post above and getting good power utilisation rate now (around 5.5 - 7W which should give close to 10hr battery life).

echo 'power' | tee /sys/devices/system/cpu/cpu*/cpufreq/energy_performance_preference

I will write up an install guide for Devuan for the laptop soon, but looks really good and should improve even further with new kernel releases.

I am trying to access power profiles for AMD laptop (thinkpad 14s Gen4 AMD).

Devuan daedalus works well in general on this laptop but trying to set power profiles fails.

install:

apt install power-profiles-daemon

try to access power-profiles:

# powerprofilesctl get
Failed to communicate with power-profiles-daemon: g-dbus-error-quark: Error calling StartServiceByName for net.hadess.PowerProfiles: Launch helper exited with unknown return code 1 (25)

looks like the service is not running.

There is no sysvinit definition but there is a systemd unit file:

[Unit]
Description=Power Profiles daemon
Conflicts=tuned.service auto-cpufreq.service system76-power.service
Before=multi-user.target display-manager.target

[Service]
Type=dbus
BusName=net.hadess.PowerProfiles
ExecStart=/usr/libexec/power-profiles-daemon
Restart=on-failure
# This always corresponds to /var/lib/power-profiles-daemon
StateDirectory=power-profiles-daemon
#Uncomment this to enable debug
#Environment="G_MESSAGES_DEBUG=all"

# Lockdown
ProtectSystem=strict

ProtectHome=true
ProtectKernelModules=true
PrivateTmp=true
RestrictAddressFamilies=AF_UNIX AF_LOCAL AF_NETLINK
MemoryDenyWriteExecute=true
RestrictRealtime=true

[Install]
WantedBy=graphical.target

running the command directly does allow access to power profile:

/usr/libexec/power-profiles-daemon

I am looking to create a sysvinit file for this daemon.  I think I can do that with just the daemon command, but not sure if it should be connected to Dbus more explicitly?

#7 Re: Freedom Hacks » ZFS with openrc - conflict with "Breaks: openrc" » 2023-04-07 05:57:46

rc-status zfs-import shows:

* runlevel `zfs-import' does not exist

I also had to run /sbin/modprobe zfs manually after start or else the zfs module is not loaded.

The module loading on boot can be fixed by editing /etc/modules and adding the line:

zfs

Interestingly, when installing openrc, it finds a dependency loop which it cleans up, I guess this is causing the zfs module not to be loaded on boot:

 
 * Found a solvable dependency loop: mountall-bootclean.sh p> mountall-bootclean u> zfs-import a> checkfs n> mounta
ll.sh p> mountall n> mountall-bootclean.sh.
 * Solving the loop by breaking mountall-bootclean u> zfs-import.
 * Found a solvable dependency loop: mountall.sh p> mountall u> zfs-import a> checkfs n> mountall.sh.
 * Solving the loop by breaking mountall u> zfs-import. 

I have also added an issue in the zfsonlinux packaging project: https://github.com/zfsonlinux/pkg-zfs/issues/238

p.s. I checked if the dependency on init-system-helpers was an issue, but that doesn't seem to be the case, openrc does not remove that package

I am trying to migrate some Devuan (Chimaera) systems from sysvinit to openrc.  The main reason is to make installing k3s easier (as it depends on openrc or systemd).

I have tested the basic process of switching to openrc on a KVM machine and it went well with just:

apt install openrc

However, on my systems that have ZFS installed, there is a conflict with zfsutils-linux breaks: openrc.

So apt/aptitude refuses to install without removing ZFS.

Since Devuan is using a backwards-compatible version of openrc, I believe it should be fine to install while preserving ZFS.

I'm not sure how to proceed.  I guess a quick and dirty fix would be to edit the entry in /var/lib/dpkg/status and remove the Breaks: openrc
Probably a better method is to recompile zfsutils-linux with checkinstall.

Would be keen to hear suggestions of the best approach and if anyone knows why the conflict is present in the package description?

We have found a workaround using the netist CD image:

Download the netinst image and mount

cd /zpool1/kvm/ISO
wget -N https://mirror.leaseweb.com/devuan/devuan_chimaera/installer-iso/devuan_chimaera_4.0.0_amd64_netinstall.iso
mount -t iso9660 -o loop ./devuan_chimaera_4.0.0_amd64_netinstall.iso ./mount/

use an alternative location and specify the cdrom disk

--location='/zpool1/kvm/ISO/mount/,kernel=boot/isolinux/linux,initrd=boot/isolinux/initrd.gz' \
--disk path=/dev/loop0,device=cdrom,readonly=on

We have tried with the following:

virt-install \
  --virt-type kvm \
  --name=guest \
  --description=desc \
  --vcpus=2,maxvcpus=8 \
  --ram=2048 \
  --disk path=/dev/zvol/zpool1/images/guest,size=40G,format=zfs,io=threads,cache=writeback \
  --memorybacking source.type=memfd,access.mode=shared \
  --location='https://pkgmaster.devuan.org/devuan/dists/chimaera/main/installer-amd64/' \
  --initrd-inject=/zpool1/kvm/preseed/cfg_devuan_chimaera/preseed.cfg \
  --network network=$net_in,mac=$mac_in \
  --os-type=linux \
  --os-variant=debiantesting \
  --graphics=none \
  --extra-args 'console=ttyS0'

We also tried updating the osinfo database:

apt install libosinfo-bin
apt install osinfo-db-tool
wget -O "/tmp/osinfo-db.tar.xz" "https://releases.pagure.org/libosinfo/osinfo-db-20220214.tar.xz"
osinfo-db-import --local "/tmp/osinfo-db.tar.xz"

and using `--os-variant=debian11` but got the same kernel mismatch issue

Any suggestions as to how we can get a Chimaera installation automated with virt-install?
