Hi Michael,

Thank you,  this is enough for me to solve the original issue in lsp-mode
repo.

As a side note, if you do search for /bin/ls executable-find will work
although it is not prefixed with the remote identifier. This is what
confused me initially.

This is a configuration setting for lsp-mode when the server is located
on the remote server. Some users dont have admin access on the remote
machine so they put the binary somewhere else so they have you use full
path.

Thanks,
Ivan
