[Snap][Service]Service in snap can not work, because there is no default path of config file

[yangyankui]

there is no default path of config file,
therefore i can not use
snap start shadowsocks-rust.ssserver-daemon

debian 10,
snap,
shadowsocks-rust edge v1.11.2.r34.gf717984

You can use arguments as a temporary solution. Ref #617.

shadowsocks-rust.ssserver -s "0.0.0.0:8388" -m "aes-256-gcm" -k "********"

Thank you!
Now, I am using
shadowsocks-rust.ssserver -c config.json
Is there any plan to support the default path?
Hope to add the function of the default path of config file.

Unfortunately, I don't have a build environment for snap.

If you keep this issue open, other collaborators may be able to fix it.

Ok, Thank you!

I recommend to set the default path to ~/.config/shadowsocks-rust.

[yangyankui]

shadowsocks-libev default path is /etc/shadowsocks-libev/config.json

Why snap's daemon couldn't start with command line arguments?

[kallydev]

shadowsocks-libev default path is /etc/shadowsocks-libev/config.json

The snap default only allow application to access path under $HOME, unless the application is installed using the --classic parameter.

Same problem here. It seems snap version can't automatically read configure file via a default or designated path as in Shadowsocks-libev. Neither can it pass parameters to its daemon service when invoking systemctl. Both of these methods are not currently working in the snap store version.

It should already supported in the latest version:

shadowsocks-rust/bin/common/config.rs
