If sh is not bash, some builtin command behave slightly differently. E.g. if sh is provided by busybox, its builtin test command does not check if the path is a mount point or not, and 'test -w' only checks the access mode of the inode. So, even if a readonly filesystem is mounted on a directory, the test command may succeed. To avoid such confusion, let's unconditionally use bash.
