[PATCH 02/31] Some dracut cleanups and bashification.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a simple getarg function.

If we ever need to get more than one kernel command line argument, this
function will pay for itself.  It relies on a feature of the way bash
handles string comparisons in [[ ]] statements -- the RHS is matched
according to globbing rules, and is not a straight string match.
