# User can specify an sname without @hostname
# This will fail when creating remote shell
# So here we check for @ and add @hostname if missing
case "${NAME}" in
*@*) ;; # Nothing to do
*) NAME=${NAME}@$(relx_get_nodename);; # Add @hostname

The issue may have been fixed in Erlang as now this works:
$ erl -sname a -setcookie a
(a@rosa) 1>
$ erl -remsh a -sname b -setcookie a
(a@rosa)1>
I think it used to not work but would want to confirm and find the patch to OTP that fixed it before starting down the path of removing it (once the oldest supported version works).
Seems it also works for longnames now:
$ erl -name a -setcookie a ─╯
(a@rosa.lan)1>
$ erl -remsh a -name b -setcookie a ─╯
(a@rosa.lan)1>
To work around an issue with resolving the hostname being different depending on if you were running a new node or a remote shell we have this code https://github.com/erlware/relx/blob/ad37eef266104872da726db27b4c729f68ffa4b1/priv/templates/extended_bin#L666
