Try to remember last action and #RTFM: start by asking a nice man about #ldconfig.

Problem here is the cache file is corrupt. We need a new one.

- enter rescue mode, get access to the net, install #emacs
- decrypt root partition, mount it on /mnt
- edit a custom /tmp/ld.so.conf with the correct paths to /mnt
- create a new /etc/ld.so.cache with

ldconfig /mnt/lib /mnt/usr/lib -f /tmp/ld.so.conf -C /mnt/etc/ld.so.cache

- reboot
- ban sudo
- stop doing #stupidshit

Lucky this time.
