is there a bug in cp command ?

["Uwe-t@online.de" <uwe-t@online.de>]

hi,

i try to use

cp -ax / /mnt
(cp space -ax space / space /mnt)

which in debian 9,10,11 worked fine

but in debian 12 (and lmde 6 (LinuxMintDebianEdition)) it does not work.

the error is:

#root@Server001:~# cp -ax / /mnt
#cp: das Verzeichnis '/mnt/' kann nicht angelegt werden: Datei oder
Verzeichnis nicht gefunden

translated: the subdir /mnt/ cannot be created. file or subdir not found.

i try to copy a ext4 filesystem to an second disk with ext4 filesystem.

you can try with and without mounting a disk to /mnt

the error is always the same.

is it a bug or a new feature ?

best regards

uwe t
