Hi there,
When running dropbear with the flag -e ("Pass on server process environment to
child process"), I noticed that the PATH variable still was not inherited.
This is due to PATH unconditionally being set inside of `svr-chansession.c`:
```c
if (getuid() == 0) {
addnewvar("PATH", DEFAULT_ROOT_PATH);
} else {
addnewvar("PATH", DEFAULT_PATH);
}
```
Is this behaviour intentional?
If not, what should the behaviour be? That if `-e` is set
(svr_opts.pass_on_env), PATH should only be set to the default value if it does
not already have a value from the environment?
If it is, would a patch adding a non-default compile-time flag that changes
this behaviour be accepted?
My use-case is that I would like to run a dropbear server which inherits the
PATH environment variable from the executing environment, but the value of this
environment variable is not known at compile time.
Thankful for your input,
