[arch-general] strange behaviour of pacman, what did I do?

[Shridhar Daithankar]

Hi

I was updating an archroot, created with mkarchroot to play with lxc. I thought following 
would work but it was doing something else altogether

------------------------
[root at bheem lxc]# pacman -Su -c /var/cache/pacman/pkg/ --root=$PWD/server1
Cache directory: /var/cache/pacman/pkg/
Packages to keep:
  All locally installed packages
Do you want to remove all other packages from cache? [Y/n] ^C
Interrupt signal received
------------------------

I think I lost a few packages during this because following command lead to a 30MB worth of 
download.

------------------------
[root at bheem lxc]# pacman -Su --cachedir=/var/cache/pacman/pkg/  --root=$PWD/server1
------------------------

What did pacman do the first time? The man page does not have bare -c option and it wasn't 
-Sc where it started cleaning the packages(or was it?)

And just to be sure.. I wanted to run pacman on the host again.. and eh? I lost my synced 
dbs? Thats strange..
