/dev/.initramfs/ is afaik created by the initramfs-tools during boot. if you
want to investigate more search for your initramfs scripts and take a closer
look at it. The same is for /dev/.udev

Maybe you should take a closer look on the other files and see whats inside of
them - but I guess they will be fine too:

/etc/.pwd.lock /dev/.static
/usr/lib/xulrunner/.autoreg
/lib/init/rw/.ramfs
