dizzy 1.7 udev automount misbehaviour

dizzy 1.7 udev automount misbehaviour

I have built an image using yocto dizzy 1.7 running on beaglebone using
systemd as init system and I noticed a misbehaviour while inserting
different removable storage device (sd cards /usb sticsk) using
vfat/ext3/ext4 FS that it does not correctly get mounted and the mount
points under /run/media/$name stay empty.

I debugged the automount script triggered by udev on insert/remove :
/etc/udev/scripts/mount.sh and it seems that it's correctly running and
mounting the media but somehow something is running after and unmounting it
and leaving the mount points empty !

This behaviour is NOT observed with yocto daisy 1.6.

Any help/hint is appreciated !

Hi Yocto,

For the record the issue is in current dizzy branch and occurs when using
systemd and udev along with udev-extraconf mount scripts.
By default, systemd-udevd.service has the option MountFlags=slave,
which means that mounts are only seen by udevd process.
This explains some weird behavior. I'll file a bug for that.

One solution is to change MountFlags to shared, so that mounts become
available for all the system.

Regards,
Michaël
