Comment 2 Igor Gnatenko 2013-09-01 11:20:23 UTC
After add support we also should add rootdelay=3 to kernel string if we use bcache on rootfs.

Comment 3 David Lehman 2013-10-14 19:31:54 UTC
Please open an RFE to add bcache support to python-blivet. This bug will be blocked by that one.

Comment 4 Rex Dieter 2014-01-28 14:51:29 UTC
rebasing (missed f20 target)

Comment 5 Rolf Fokkens 2015-01-04 14:15:10 UTC
Given the fact that serious changes on bcache are planned, I think this change should be postponed until further notice:

Comment 7 Micah Roth 2018-11-09 01:23:20 UTC
it appears the serious breaking changes discussed in those threads have all been migrated to a new project called bcachefs; Kent seems to regard bcache as it is as stable. https://bcache.evilpiepirate.org/ 

my read is bcachefs is a superset of bcache that includes a whole bunch of other stuff, but bcache will continue to be improved because it addresses a more specific need. 

my brief experiences with bcache have been very positive and i'd love to see it in the installer. can i help?

Hello Micah, right now we are still blocked by the bug 1019442 . Without that implemented we can't support it in Anaconda.
