I just upgraded my RPi B from
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.
- 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?
