# 99effsyno - a script for Synology
|
|
|
|
DSM sucks. I hate it. I absolutely hate what it does to the underlying operating system. I hate how idiotic it is
|
|
regarding mounts. I hate how things are it's way. I mostly hate it because I didn't ask for pay for these features
|
|
and they seemingly give you no way of telling them to GTFO.
|
|
|
|
99effsyno is just a couple of things that make the synology do *the absolute minimum* I expect to be able to do. It's
|
|
name comes from the shell script used to achieve this; 99 is just an execution priority, effsyno is fuck synology....
|
|
because fuck DSM.
|
|
|
|
## What sucks
|
|
|
|
I have a USB enclosure that holds a lot of disks. By default...Synology mounts any valid partition to
|
|
`/volumeUSB*n*/usbshare` where *n* is the number assigned. It then automatically creates a samba share configuration
|
|
that shares it as usbshare*n*...where *n* is once again the drive number.
|
|
|
|
This is all you're given. You cannot rename the share in DSM, you cannot move it.
|
|
|
|
To complicate this, while I can achieve exactly what I want to do through standard command line hacking, these changes
|
|
don't persist between reboots. The two biggies are `/etc/fstab` and samba configurations are generated dynamically. So
|
|
the idea of just adding the UUID to `/etc/fstab` and modding `/etc/samba/smb.share.conf` the usual way are out.
|
|
|
|
## Other Oddities
|
|
|
|
They seem to have a lof of abstraction between you and the hardware. My internal RAID1 is actually LVM2 on /dev/md2. This
|
|
sucks because it adds another layer of useless complexity if I want to remount this later. I mean it can be done...I just
|
|
have to look all that up. It's going to happen...I'm not sticking with this hardware for long.
|
|
|
|
I also noticed that even manual mounts from command line have a systemd service created for them. No...I want out.
|
|
|
|
## The Hack
|
|
|
|
While it generates a lot of configs and wipes directories out on boot, I did find one little trick that still worked:
|
|
`/usr/local/etc/rc.d` - We can stick shell scripts here, they'll run at boot, and they'll persist between reboots.
|
|
|
|
There are two files: `99effsyno.sh` and `smb.sh`. The `smb.sh` file is not actually a script. I only gave it the .sh filename
|
|
to ensure it didn't get deleted. This is actually our replacement samba configuration. *This file should not be +x!*
|
|
The original varient had a simple exit routine and tail command to output just the .conf; this is easier.
|
|
|
|
`99effsyno.sh` is the executable script that does the following:
|
|
|
|
* mounts the external drives by UUID to points I specify
|
|
* replaces the samba share configuration
|
|
* reboots samba
|
|
|
|
## At Your Own Risk
|
|
|
|
Don't do this. I'm not taking responsibility and Synology will tell you to GTFO and never give you support again.
