docker build places the binary in /root folder
I am not sure in which scenario binary would be missing...

[krombel]

The issue is, that we call netclient via /root/netclient and via netclient directly (which would require /root to be in $PATH which is not the case)

netclient/Dockerfile

Line 20 in 3fa8249

COPY --from=builder /app/netclient-app ./netclient

netclient binary is copied to /root and then installed via startup script

[krombel]

netclient install is using /root/ (so not needing this patch) but netclient join relies on PATH and is failing currently

[abhishek9686]

netclient install will put the binary in /bin path, so full path reference is not required
