What is the output from 'df -Th' ? I appreciate any suggestions for places to look, since I am baffled. The filesystem is ext4. "df -Th /" says as much, and also says that teh filesystem is 18% full. But you're right that the filesystem is somehow involved. When I do exactly the same thing in the /run directory, which is tmpfs, it works as expected. The output from "mount" doesn't help much: /dev/md5 on / type ext4 (rw,relatime,seclabel,data=ordered) Trying this on /boot (a separate ext4 filesystem in a different disk partition) gives yet a different result; the file ends up with -r--r--r-- permission. I know that this isn't caused by selinux, because I get the same results after booting with selinux turned off. Alan Stern
