With the caveat that I haven't yet created a btrfs (seriously waiting on a Seagate RMA), I think most of the complaints on this thread are due to thinking of filesystems in old terms, due to limitations of old storage concepts. To do this right probably requires the careful use of subvolumes. One for rpm, one for logs, one for each package installed, one for each user's home, etc. From rpm you can know what needs rolling back. This probably implies foo-var, foo-etc, foo-log, foo-share, etc, which is inefficient, so maybe some refinement is needed there as well. -Bill -- Bill McGonigle, Owner BFC Computing, LLC http://bfccomputing.com/ Telephone: +1.603.448.4440 Email, IM, VOIP: bill@xxxxxxxxxxxxxxxx VCard: http://bfccomputing.com/vcard/bill.vcf Social networks: bill_mcgonigle/bill.mcgonigle -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
