>Description:
When mv moves a file it tries to set the utimes etc. on the target file. This can fail because the target lives on a filesystem which does not support permissions or seting times, for example msdosfs. It then would complain per file copied and not remove the source. This only happens though when moving a whole directory onto such a filesystem. When moving just a file, it would complain and DO remove the source.
>How-To-Repeat:
cd /tmp
dd if=/dev/zero of=msdos.bin bs=1m count=10
vnconfig vnd0 /tmp/msdos.bin
newfs_msdos /dev/rvnd0a
mkdir -p mnt
mount -t msdos /dev/vnd0a mnt
mkdir -p dir
touch dir/file1
touch dir/file2
chown -R nobody dir
mv dir mnt
echo "? : $?"
[ -d dir ] && echo "dir still exists here..."
[ -d mnt/dir ] && echo "dir also exists there..."
# output:
# ? : 1
# dir still exists here...
# dir also exists there...
>Fix:
I'd say beer but..
maybe should have a way to determine features of the target filesystem and then act accordingly? I.e. not try to set permissions/ownership on a filesystem that does not support it, not complain, not exit with 1 in that case.
