emacsclient regularly to open files. In order to open files owned by root, it is necessary to use tramp. As far as I know this requires the use of the
eval option of
emacsclient --eval '(find-file "/sudo::/etc/motd")'
But this command behaves as if I specify the option
no-wait, because the evaluation returns after the file has been opened.
Which expression needs to be evaluated in order to wait till the file has been closed?
