Hi It was brought to my attention that there's a confusing typo in the message below regarding the planning of bcache support for anaconda. The claim that it is planned for F20 is not true, it is planned for F21: https://fedorahosted.org/fesco/ticket/1145 Sorry for any confusion, Rolf Op 26-09-13 11:56 schreef Rolf Fokkens <rolf@xxxxxxxxxxxxxx>: >Hi, > >Like I did on the 14th on the linux-bcache list I'd like to send an >update on the progress of bcache related packages.
