 REQUIREMENTS:
 
 	- Linux kernel >= 2.6.27
-	  pipe2(), epoll_create1() and SOCK_CLOEXEC are needed to run the session
-	  daemon. There were introduce in the Linux 2.6.27
+	  For epoll() support, at least this version is needed. However, poll() is
+	  also supported by running "./configure --disable-epoll". Using that, the
+	  kernel version can probably be older but we can't provide any guarantee.
+	  Please let us know if you are able to go lower without any problems.
