[arch-projects] [mkinitcpio PATCH] add_{file, symlink}: overwrite existing file

[Tom Gundersen]

Now we fail silently if the file exists, which means there is no easy way to overwrite binaries.

I think it makes the most sense to do the following:
1) add all the busybox stuff as a basic system;
2) overwrite some of the links with any binaries we add to base hook;
3) allow users to write their own hooks to overwrite even more stuff.

This can now be done by this hook.

[this should have been part of the previous patch serios, it got lost on the way, sorry about that.]
