Bug#925146: grub-probe appears to be stuck (in chroot)

[Harald Dunkel]

I apologize again for not sending the log file you asked for right
from the start. Hopefully you found the second strace log file?

Of course it is vgs that got slow somehow, but AFAICS it is called
about 16 times for each grub-mkconfig, even though there are only 4
logical volumes. Grub-mkconfig was run at least 4 times during the
upgrade from Stretch to Buster (then I went home, hoping that it is
finished tomorrow morning).

Sorry to say, but something got worse with Buster here. If you
come to the conclusion that it is not a problem of grub, then please
feel free to reassign this bug report.

Regards
Harri
