Original GitHub issue: https://github.com/netblue30/firejail/issues/719

Functionality:

sftp and scp - are started outside the sandbox
simple login: ssh test@0 - the session is started with "-l" flag
simple command: ssh test@0 date - the session is started with "-c" flag
multiple commands: ssh test@0 "date && date" - the session is started with "-c" flag
1, 2, 3, 4 with or without an entry in /etc/firejail/login.users
1, 2, 3, 4 with various --shell entries in /etc/firejail/login.users

1, 2, 3, 5 are working fine. I didn't test anything for 6 yet. Currently 4 is broken. It is broken even for regular firejail sessions, example:

$ firejail -c "date && date"
Reading profile /etc/firejail/default.profile
Reading profile /etc/firejail/disable-common.inc
Reading profile /etc/firejail/disable-programs.inc
Reading profile /etc/firejail/disable-passwdmgr.inc

** Note: you can use --noprofile to disable default.profile **

Parent pid 4641, child pid 4642
Child process initialized
/bin/bash: date && date: command not found

Parent is shutting down, bye...

Hello, what's the current status of that functionality? Is firejail nowdays save to use as restricted shell?
