It's configured by /usr/lib/sysctl.d/97-kde-nepomuk-filewatch-inotify.conf which is installed by nepomuk-core, so ideally you'd get that value if you have KDE or installed a package that pulled nepomuk-core as a dependency.

I have another question......

I just did a "yum erase nepomuk-core" on a system and /usr/lib/sysctl.d/97-kde-nepomuk-filewatch-inotify.conf was removed since it was owned by nepomuk-core.

Upon reboot of the system ....

[egreshko@f20kde ~]$ ls /usr/lib/sysctl.d/
00-system.conf  50-default.conf  libvirtd.conf
[egreshko@f20kde ~]$ cat /proc/sys/fs/inotify/max_user_watches
524288

So, it seems that file isn't really needed in F20 at this time to raise the limit?

/usr/lib/sysctl.d/97-kde-nepomuk-filewatch-inotify.conf is included in the initramfs by dracut when a kernel is installed/updated. Check `lsinitrd /boot/initramfs-$(uname -r).img | grep sysctl`.

So in effect you'd have to re-create the initramfs after uninstalling nepomuk-core to make that custom setting go away completely.
