Windows shares

New to LE, but been using Raspbmc/OSMC for years :-}
I thought I'd have a look at LE and bumped into a couple of issues.

On OSMC I mount my media, which is on a Windows box, by editing /etc/fstab to automount the various shares.
I have several different media libraries which use different shared MySQL databases on the same Windows box.
The reason for the multiple databases is for different users [profiles] with different media.
[e.g I keep the Opera etc. separate from movies/TV].

So - the issue. In the MySQL databases, paths are of the form /media/sharename/dir1/dir2 .....
This works because of the automounting mentioned above.
This clearly won't work on LE as I can currently only access the shares via smb://server/share/.....

Is there a way for a user-defined script to be run on startup?

Secondary question - in /etc/fstab I had entries of this form:
//http://192.168.xx.yyy/XBMC /media/zbmc cifs credentials=/.smb/.agb noserverino,file_mode=0777,dir_mode=0777,sec=ntlmv200

I haven't managed to get the equivalent manual mount commands to work.

Any help/advice appreciated.

Oops, forgot version info [although I think this is probably a generic problem].

Q1 Make an advancedsettings.xml file and stick a path substitution (have a look in the kodi wiki for details and examples).

Q2. No idea.

I'm not clear why you need multiple mysql databases (or why you need to mount for that matter) - it sounds like smart playlists would be an easier way to separate content.

The separate libraries/databases are mainly to keep the number of entries manageable and maintain separate watched status.
I use path substitution for other purposes, don't want to use smb:// paths in the databease, assuming the substitution
could be made to work.
I use smart playlists in the various profiles to subset the content via menus in the skin.
Automounting avoids issues when switching profiles, as learned from bitter experience.
I may have to use the technique of tweaking the squashfs as described here squashfs howto - make changes the read-only filesystem in OpenELEC - andreierdei
if there's no other way to get the shares automounted.

Thanks anyway.

One thing: Using the /etc/fstab file is not the best solution as it will be overwritten with any upgrade (or downgrade) of LibreELEC. Either use autostart.sh with manual mount commands, or edit the smb.cnf file in /storage/.config (from the top of my head).

Aha! I'll have to investigate autostart.sh, thanks.
Still having trouble mounting a share manually, so will have to resolve that.
I'm aware that /etc/fstab will get zapped, hence the reference to squashfs howto - make changes the read-only filesystem in OpenELEC - andreierdei
in my last post.
Can't find /storage/.config/smb.cnf - there's only a samba.conf.sample in there.
Thanks anyway.

Found the answer here:
LibreELEC
I'll set up some system.d services.
Thanks all.

The reason I want to mount the shares outside of kodi is that I want them available across all profiles.
*And* I want the pathnames for media to be of the form /media/share/etc/etc not smb://server/share/etc/etc.
I appreciate that this may be a non-standard/unusual requirement :-} but it *is* my requirement.

I use the same media and MySql dbs on OSMC.
I have things working this way on OSMC and I would like LE to work the same way :-}

Using systemd services I have got it all working now.
The only fly in the ointment is that sometimes the mounts fail. I am fairly sure that this is because the Pi
hasn't got the correct time from ntp yet, but I work around it by rerunning the mounts from a script.

donbrew
Not sure what you mean by 'gets the time from your LAN' :-}
It gets it from an NTP server *somewhere* - be it your router, or in my case, the NTP servers specified by my DHCP server.

I already have the 'wait for network' setting set, but the problem I am seeing is that the time doesn't get sync'd until a while after kodi starts, which is after the systemd mount services have already failed, as the Pi's time seems to be set from the kernel build time, as milhouse has explained some where.

It isn't a showstopper, as I just SSH in and and rerun the mounts - this is OK on my 'development' Pi but would not be OK on the 'family' Pi :-}

donbrew
I don't think that's quite how it works, but no point arguing about it :-}
For the purpose of this discussion, the problem is that the Pi doesn't set its clock to the correct time before the network mounts are attempted.
I've started another thread about Time synchronisation.
