low-end persistence strategies?

[Michele Simionato]

Uhm ... I reading /usr/src/linux-2.4.27/Documentation/mandatory.txt
The last section says:

"""
6. Warning!
-----------

Not even root can override a mandatory lock, so runaway processes can
wreak
havoc if they lock crucial files. The way around it is to change the
file
permissions (remove the setgid bit) before trying to read or write to
it.
Of course, that might be a bit tricky if the system is hung :-(
"""

so lockf locks do not look completely harmless ...
