Unescape issue with systemd and multiple processes

[cbillen]

With systemd setup to install multiple processes, we run into the following error when deploying

01 Invalid unit name "sidekiq@{1..4}" escaped as "sidekiq@\x7b1..4\x7d" (maybe you should use systemd-escape?).`

Regardless of the task, it seems that anytime systemctl_command is called without a process and the @{ ... } is appended it gets escaped somehow.

My capistrano sidekiq is configured as such:

set :sidekiq_roles, :worker
set :sidekiq_default_hooks, true
set :sidekiq_processes, 4
set :sidekiq_config, [
'config/sidekiq.yml',
'config/sidekiq_high.yml',
'config/sidekiq_low.yml',
'config/sidekiq_campaign.yml'
]
set :sidekiq_env, -> { fetch(:rack_env, fetch(:rails_env, fetch(:stage))) }
set :sidekiq_log, -> { File.join(shared_path, 'log', 'sidekiq.log') }
set :sidekiq_error_log, -> { File.join(shared_path, 'log', 'sidekiq_error.log') }
set :sidekiq_user, 'deploy'
set :sidekiq_service_templates_path, 'config/deploy/templates'

set :sidekiq_service_unit_user, :system

SSHKit.config.command_map[:sidekiq] = "bundle exec sidekiq"
SSHKit.config.command_map[:sidekiqctl] = "bundle exec sidekiqctl"

Server runs Ubuntu 20.04

I can run the command directly on the server, it's just when done through SSHKit

Is there a workaround?
