Hi,
Windows 7
GNU Emacs 26.0.50 (build 1, x86_64-w64-mingw32) of 2017-08-27
(backup-by-copying t)
When I tramp to a host (linux) and edit a file, and save it, I get an error about the backup as below. The ACL is in different format on Linus and on Windows. It is "user::..." on linux, however, it looks like "O:S-1-5-21-" on windows.
Could we allow the user to set whether to copy ACl for certain type of files?
Debugger entered--Lisp error: (file-error "Converting ACL" "Invalid argument" "c:/Users/user/HOME/.emacs.d/autosave/Rfiles/!drive_c!plink!!user@host!!!path!user!Ava!_mortality.R.~1~")
