[PATCH] dracut: setup English locales for Dracut build script

Dracut rely upon programs' output like ldd's "not a dynamic executable".
Assume user sets up Polish locales and then ldd prints
"nie jest dynamicznym programem wykonywalnym".  The patch prevents this.

Hmmm... The usual way to do this is to run the program in the C locale
by setting
LC_ALL=C

I don't have any en_US locales installed on my system. Not sure why a Pole 
would either. You'd probably be better off with the "C" locale, IMHO.

You mean we should prefix every call which output we rely or just setup:
export LC_ALL=C in place I pointed?  Hm… to think about it the first
option would be more elgant.

Hmm, we probably should prefix every call to an app, where we parse the output 
with LANG=C like this:

LANG=C ldd $file | grep -q "not found"

Thank you all for comments.  Right, C is better. :-)

I reviewed the code and it looks that only ldd is “affected” by locales,
although there some other commands the output is parsed, but it's not
localized.  Should we prefix them anyway “just for sure” or leave as is?


Cheers,
