From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.6) Gecko/20011120 Description of problem: xfs runs with its cwd set to the last fontpath element from /etc/X11/fs/config. This is bad if you have a remote filesystem with fonts on it - you can never umount the fs if xfs is running. If it's automounted it will never umount automatically. The init script bit that iterates over the font paths is the culprit. Changing the script so xfs's cwd is / should be easy. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. run xfs 2. look at /proc/<xfs pid>/cwd - it's set to the last font element Expected Results: xfs's cwd should be /. (or something less likely to be on a remote fs at least.) Additional info:
This sounds reasonable to me. I've fixed the init script, and am attaching a copy here for you to try. Please update the report and let me know if this fixes the problem for you.

Well...not quite right I think. I'd have just put "cd /", as the pushd/popd will leave the cwd to be whatever dir you were in when the service is started. There is no need to preserve where we were. For example if you had a cd mounted, were in that dir when you restarted xfs for some _stupid_ reason [or not so stupid, I copied some .ttf files off the cd maybe and don't know about xfs restart :) ]. Later on I wanted to umount the CD -- mountpoint is busy. I just did this with an automounted cdrom: (58)ehuff-linux[~] cd /misc/cdrom (60)ehuff-linux[/misc/cdrom] sudo service xfs stop Shutting down xfs: [ OK ] (61)ehuff-linux[/misc/cdrom] sudo service xfs start Starting xfs: [ OK ] (62)ehuff-linux[/misc/cdrom] cd (63)ehuff-linux[~] sudo umount /misc/cdrom umount: /misc/cdrom: device is busy daemons should have a cwd of / in general, or some dir where they own everything (maybe /etc/X11/fs for this case if anything). This is really something xfs should do after it forks, right after closing stdout and stdin like a good daemon should...
I've created a patch for xfs which chdir()'s before fork(), and submitted it to XFree86.org for inclusion in upstream CVS.
My patch is now in rawhide XFree
