For some reasons the problem recently reappeared in CVS Emacs: The file /path/to/example on host bob is owned by root.foo visiting it from another host as /ssh:root@bob:/path/to/example editing and saving leads to it being owned by root.root. I have backup-by-copying set to t. Any Ideas?

No, at a quick test it didn't. I applied your patch (assuming it were an revert patch), reevaluated backup-buffer-copy, visited and saved a remote file, but with the same result, the group was changed... cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 Intevation GmbH, Osnabrück http://www.intevation.de/~wilde/ Amtsgericht Osnabrück, HR B 18998 http://www.intevation.de/ Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner [-- Attachment #1.2: Type: application/pgp-signature, Size: 188 bytes --] [-- Attachment #2: Type: text/plain, Size: 143 bytes --] _______________________________________________ Tramp-devel mailing list Tramp-devel@gnu.org http://lists.gnu.org/mailman/listinfo/tramp-devel ^ permalink raw reply [flat|nested] 5+ messages in thread

In fileio.c, Fcopy_buffer calls the file name handler without preserve-uid-and-gid. I've committed the patches for files.el and fileio.c to the Emacs trunk.
