If you keep a dummy file whose modification date indicates when the service was restarted, you can figure out whether FILE or the dummy file is newer. If FILE is newer then it was modified after the service was last restarted. But it requires the discipline that you update the timestamp of the dummy file each time you restart the service.

BOOTPARAMS(5)                                                 BSD File Formats Manual                                                BOOTPARAMS(5)

NAME

     bootparams -- boot parameter database

SYNOPSIS

     /etc/bootparams

DESCRIPTION

     The bootparams file specifies the boot parameters that diskless clients may request when booting over the network.  Each client supported by
     this server must have an entry in the bootparams file containing the pathnames for its root and (optionally) swap areas.

     Each line in the file (other than comment lines that begin with a #) specifies the client name followed by the pathnames that the client may
     request by their logical names.  The components of the line are delimited with blank or tab, and may be continued onto multiple lines with a
     backslash.

     For example:

           dummy   root=host:/export/dummy/root 
                   swap=host:/export/dummy/swap 
                   dump=host:/export/dummy/swap

     When the client named "dummy" requests the pathname for its logical "root" it will be given the pathname ``host:/export/dummy/root'' as the
     response to its RPC request.  The "host:" component must be supplied.
