[Lunar-commits] CVS: moonbase/filesys/udev POST_INSTALL,1.3,1.4

[Jaime Buffery]

Update of /var/cvs/lunar/moonbase/filesys/udev
In directory espresso.foo-projects.org:/tmp/cvs-serv26432

Modified Files:
	POST_INSTALL 
Log Message:
Added ram0 (with ram symlink) and ram1 needed for booting ramdisks, 
since udev will not be running yet at that time of the boot. Symlink
support has been added, and some cleanup has been done too.
