Greyhole Locally Mounted Shares

Could I get some help mounting the greyhole shares locally please?
Guillaume has a script for Deb & Fedora, but I've no clue how to translate that for Arch.

Here's Deb/Ubuntu

exit $?

I tried simply using /etc/fstab to mount the shares (run of the mill cifs mount line for fstab), and while in the environment a "mount -a" does indeed work fine, but as I suspected, upon startup and or shutdown things get messed up (due to the order of operations, I'm pretty certain).

Anyone up for figuring this out? A group of media shares does me no good if Plex can't see them.

Re: Greyhole Locally Mounted Shares

Super old necro-post, I know. Just wanted to shed some light on this as I just encountered this issue myself.

The mount_shares_locally script parses smb.conf for samba shares and then mounts them via mount.cifs. This can easily be done in fstab using x-systemd.requires=greyhole.service, which in turn requires smb.service. For example:

# mount the greyhole drives
/dev/hdd0 /mnt/hdd0 ntfs-3g defaults 0 0
/dev/hdd1 /mnt/hdd1 ntfs-3g defaults 0 0
# note TestShare is the landing zone on /mnt/hdd0/shares/TestShare in this case, as defined in smb.conf

# mount locally
//127.0.0.1/TestShare /mnt/samba/TestShare cifs x-systemd.automount,x-systemd.requires=greyhole.service,credentials=/home/<user>/.smb_credentials,file_mode=0777,dir_mode=0777 0 0
