is there any risk replacing SSH servers' defualt shell in EXEC Channel ?

[dgu]

Hello!

I want to pass environment variables without using ChannelExec#setEnv methods. Instead, I want to pass them in a single line to sh shell as below:

channelExec.setCommand("/bin/sh -c 'ENV1=val1 ENV2=val2 command'");

It works; but it creates another shell. I don't want to create another shell and replace the current shell used by SSH server. I did as below:

channelExec.setCommand("exec /bin/sh -c 'ENV1=val1 ENV2=val2 command'");

It works.

I want to be sure that replacing default shells of any SSH servers are a supported way.

is there any risk replacing SSH servers' defult shell ?

Thanks in advance!
