Hello, everyone.
( I post to this mailing list again after an interval of 15 years. :-) )
The touch command included in busybox (version 1.30.1-6) on OpenWrt does not
have the option "-h".
Therefore, the tramp-sh-handle-set-file-times function does not work properly
if the argument flag is nofollow.
Could you please add the connection-property "touch-h" to fix the problem?
(I attach a sample patch based on TRAMP 22.1 for Emacs 30.1.)
