ConnMan writes stats and history files for each configured interface to
/storage/.cache/connman/*/{data,history}. These files remain open while
ConnMan is running, and prevent the system from halting or rebooting
when /storage is an NFS mount (because ConnMan brings down the interface
through which the NFS mount is accessed and then tries to update the
stats and/or history file for that interface, but the file descriptors
are no longer valid, so the system hangs).
The stats and history files are superfluous, especially since the means
of viewing them isn't included in LibreELEC (the stats tool is missing
because ConnMan is compiled with --disable-tools), so there's no harm in
not generating them on systems that don't mount /storage over NFS
either; in fact, it benefits LibreELEC installations where /storage is
mounted on a flash device by reducing unnecessary flash writes.
The init script currently touches a file at /dev/.storage_netboot if
/storage is a remote filesystem, so that scripts that run after the root
filesystem has been switched can behave differently depending on whether
/storage is mounted locally or remotely. Add similar functionality for
/flash by touching /dev/.flash_netboot if it is a remote filesystem.
find_file_path has to be put into an if, otherwise its return
code (which is usually 1) will leak into post_makeinstall_target
