Re: [fuse-devel] Side effect change current working directory

[Johannes M. <dn...@gm...>]

Hi again,

I confused the condition in the last mail; The condition to reproduce
the behaviour is not to use the foreground option.
Before bothering with a problem that might be part of my own code, I put
some more effort into the location of the problem. This was not straight
forward, as the working directory is not changed directly after calling
fuse, which made me doubt myself for a minute :)
I modified the loopback example file system to reproduce the behaviour:
https://gist.github.com/joe42/dd0032e9470748842cb9

gcc -Wall fusexmp_fh.c `pkg-config fuse --cflags --libs` -lulockmgr -o
fusexmp_fh
mkdir d
./fusexmp_fh d
echo hi > d/tmp/test
cat /tmp/fuse_log

This should show the current working directory to be root ("/").

Regards,
Johannes Müller
