Bug Description
When performing install audits of yesterday's 12.04 isos, I found the following odd directory on servers:
$ ls -ld /media/
drwsrwsrwt 3 root root 4096 Apr 13 06:06 /media/
In 11.10 we had:
drwxr-xr-x root root
The desktop install does not seem to be affected:
$ ls -ld /media/
drwxr-xr-x 2 root root 4096 Apr 12 02:42 /media/
Other directories:
drwsrwsrwt 2 root root 40 Apr 13 06:59 /run/initramfs/ (desktop and server)
drwsrwsrwt 2 root root 4096 Apr 13 07:21 /var/lib/
Some odd files:
crw------T 1 root root 10, 235 Apr 13 07:18 /dev/autofs
crw------T 1 root root 10, 234 Apr 13 07:18 /dev/btrfs-control
crw------T 1 root root 10, 184 Apr 13 07:18 /dev/cpu/microcode
crw-rw-rwT 1 root fuse 10, 229 Apr 13 07:18 /dev/fuse
crw-rw-rwT 1 root root 10, 200 Apr 13 07:18 /dev/net/tun
crw-rw---T 1 root audio 116, 1 Apr 13 07:18 /dev/snd/seq
crw-rw---T 1 root audio 116, 33 Apr 13 07:18 /dev/snd/timer
Server files were observed after first boot of a amd64 server install (non-MAAS) with encrypted home and all (non-manual) tasks installed in a kvm VM. All other options were defaults.
Desktop files were observed after first boot of a amd64 livecd install with encrypted home and 3rd party addons selected in a kvm VM. All other options were defaults.

/run/initramfs would be a problem (non-rlimitable DoS due to memory use), but I can't reproduce that on desktop.
