FUSE is crazy

+
+ Posted on 2010/11/01 by lts +

+

Well, I suppose just I’m only talking about Linux FUSE, I haven’t fiddled with FUSE on any other kernel. Anyway, FUSE screws with the idea of the root user:

+
$ ls
+Makefile
+build.log
+...
+$ sudo ls
+ls: cannot open directory .: Permission denied
+$
+

For those who don’t get it, the user with user ID `0′, usually with the username `root’ is the supreme administrator account — it is locked out of nothing, the kernel doesn’t even check file permissions when the user is root. The sudo (switch user do) command runs the following command as root. Anyway, even though the kernel doesn’t check file permissions when the user is root, FUSE does, in fact, it forces a umask of 0077, which means that even if the file permissions say “anyone logged in can read this file”, only the owner of the file can actually read it. I’m sure that this can be configured, but that doesn’t mean that it’s not brain damaged by default.
