Mounting subvolume as /srv

Hello

How to configure /etc/config/storage (or other config file) to mount subvolume of SSD (I have whole system running from SSD) as /srv?
When /srv is placed directly on root of SSD (@ subvolume) I have problems with snapshots (I ran out of space today, had to remove some snapshots).

mount-points are set in /etc/config/fstab

And how to apply this settings (without reboot)?
There is no block-mount package.

try /sbin/block mount

Ok, I coultn’t install block-mount, because lists were not updated:/
Now everything works.

It doesn’t work.
/sbin/block refuses to mount subvolume of already mounted device.

block: /dev/sda1 is already mounted on /

More info here:

I’ve modified /etc/init.d/fstab and added mount command just after block mount command.
It works (propably until next TurrisOS update, we’ll see).
