tool for simulating superuser privileges


faked - daemon that remembers fake ownership/permissions of files manipulated by fakeroot processes.


faked [--debug] [--foreground] [--cleanup] [--key msg-key] [--load] [--save-file save-file] [--port TCP-port]


If a fakeroot process wants to change the ownership of a file, then faked is the process that remembers that new owner. If later the same fakeroot process does a stat() for that filename, then the libfakeroot wrapped stat() call will first ask faked for the fake ownership etc of that file, and then report it.


--debug Print debugging information on stderr.
Don’t fork into the background.
--cleanup number
Cleanup the semaphores.
--key key-number
Don’t allocate a new communication channel, but use channel specified by key. (If the specified channel doesn’t exist, it’s created).
--save-file save-file
Save the environment to save-file on exit.
--load Load a previously saved environment from the standard input.
Use real ownership of previously-unknown files instead of setting them to root:root.
--port tcp-port
Use TCP port tcp-port.


None so far. Be warned, though: although I’ve written quite a few much larger (and smaller) programs, I’ve never written anything that was as tiny as fakeroot, had as many bugs as fakeroot, and still was as usable as, say, fakeroot version 0.0_3, the first version that could be used to build itself.
