mount /dev/sdb1 dir1 mount /dev/sdb1 dir2 touch dir1/file1 touch dir2/file2
I'm worried about the collision of writing data, which may result in some corruption of the filesystem.
I read through
man mount and
man umount, but nothing about this was found. Actually,
man umount implies this(=mounting on many directories) can happen but doesn't refer to the safeness.
(I just tested the situation and, at this moment, no problem has happened.)
