I just upgraded my RPi B from wheezy to jessie. This worked fine so far. Only had some trouble with systemd, so I uninstalled it and switched back to sysvinit (I like it more anyways). Now I am on jessie, everything works as before, with one small but annoying difference:

The boot process takes around 20 to 30 seconds additionally (before it was like 10 seconds all together) on the step

Waiting for /dev to be fully populated

It switches to OK in the end and everything works, but since jessie it takes horribly long to succeed.

Additional information:

  • The Pi is running headless (SSH only, no display)
  • no USB device is attached (no WiFi dongle, no keyboard, no HDD, no whatsoever)
  • only the default stuff is mounted (SD card)

After googling a while I found out that it seems that /etc/udev is responsible for that, but I'm not sure what I have to look for. Especially, the config files in there are empty or "trivial" one-liners which I manually never touched (so I assume they are in the default state).

What device could cause this long pause on a plain Raspberry Pi? And how to speed it up again?

  • Did you have this problem before you switched back to SysV init?

  • @goldilocks Not sure. With systemd the boot was extremly slow anyways on several steps, it always bootet into emergency mode (for which I plugged a display and keyboard on, and uninstalled systemd, then removed display and keyboard again). I can't say if systemd was slow on this step as well.
