device stopped after timeout about mkinitcpio-systemd-tool

[Andrei-Pozolotin]

please test with keep alive settings
https://linux.die.net/man/8/dropbear

-K timeout_seconds
Ensure that traffic is transmitted at a certain interval in seconds. This is useful for working around firewalls or routers that drop connections after a certain period of inactivity. The trade-off is that a session may be closed if there is a temporary lapse of network connectivity. A setting if 0 disables keepalives.

This did not change anything. As far as I can tell, -K only affects open connections. The issue I'm describing here also happens without any open connection. I suspect that there is a dependency missing somewhere.

[julianbrost]

I found a workaround: adding a file /etc/systemd/system/dev-system-root.device.d/depend-on-cryptsetup.conf to the initrd with the following contents:

[Unit]
JobTimeoutSec=0
Requires=cryptsetup.target

But I'm not sure if that's the best solution and it would be nice if it just works by default.

[Andrei-Pozolotin]

an easier solution for root device timeout could be:

1. remove root=/dev/mapper/root from kernel command line

2. provide /sysroot/ folder in the /boot/initramfs-linux.img

3. declare long timeout in /boot/initramfs-linux.img/ucpio://etc/fstab:

# provide here root partition description (instead of kernel command line)
#  <file system>        <dir>      <type>    <option>                         <dump> <pass>
 /dev/mapper/root     /sysroot    auto     x-systemd.device-timeout=9999h     0     1

Two noob questions:

2. How to provide the /sysroot folder?
3. Why not x-systemd.device-timeout=0, for waiting indefinetly?

[Andrei-Pozolotin]

/sysroot: now included in service by default:
https://github.com/random-archer/mkinitcpio-systemd-tool/blob/master/initrd-cryptsetup.service#L37

x-systemd.device-timeout: there is no default, per docs:
https://www.freedesktop.org/software/systemd/man/systemd.mount.html
but please try and report back
