logfile=/run/vdev/vdevd.log

I'd rather choose

logfile=/var/log/vdev/vdevd.log

as /run/ is a ramdisk ;-)

You probably have no list of the changes you made?

I installed vdev like in INSTALL.md, but it seems to have problems.
vdev starts, but quits. It creates most devices, but does not set the
apropiate ownerships and permissions. When I start vdev manually, it
starts but refuses to set the apropiate ownerships and permissions.

But when running:

/sbin/vdevd -v2 -c /etc/vdev/vdevd.conf -l /var/log/vdev/vdev.log /dev

everything seems to work well, the apropiate ownerships and
permissions are set to the expected settings.

IOW: when run manually it's ok. It might have something to do with
initramfs which refuses to compile, due to an old bug. The workaroud is
to:

ln -s /dev/sda5 /805

in order to make it work again. But generating the initramfs from the
example directory stops with an error and an empty initramfs file. The
thing I did was symlinking the libudev.so.1

ls -al /lib/i386-linux-gnu/libudev.so.1
lrwxrwxrwx 1 root root 17 Aug 10 14:08 /lib/i386-linux-gnu/libudev.so.1
-> /lib/libudev.so.1

and to run a update-initramfs -u -v

Anyone a hint?

R.
