- Fix patch tty-ask-password-agent-on-console.patch not to crash away but enable it to ask on all devices of /dev/console - Avoid "file not found /etc/udev/rules.d/70-persistent-net.rules" waring occurring in %post - Add patch let-vconsole-setup-get-properties-only-once-to-copy-them.patch to avoid broken virtual console mapping due stressed ioctl API for the virtual consoles (boo#904214) - Fix last change that is use the new name for udev packages in %pretrans. - restore usage of LUA in %pretrans. - Try to generate the systemd users and groups always in same order to avoid republish other packages (boo#944660) - cleanup specfile by removing commands that were dealing with systemd pre-generated files: we're now using systemd tarball generated directly from the git repo which doesn't contain any of these files. - there's no point in using LUA in %pretrans - Drop 0009-make-xsltproc-use-correct-ROFF-links.patch This patch was initialy added to workaround bsc#842844. But it appears that man(1) was fixed (included since 13.2 at least) to handle manual pages that consist only of a .so directive such as '.so <page>'. - Change use-rndaddentropy-ioctl-to-load-random-seed.patch to make it work on big endian OBS-URL: https://build.opensuse.org/request/show/333777 OBS-URL: https://build.opensuse.org/package/show/openSUSE:Factory/systemd?expand=0&rev=223

Upstream: marked as openSUSE-specific fix originally, but may well
|
|
worth be to be sent upstream.

Original description:
|
|
(none)
|
|
|
|
Augmented description [jengelh@inai.de]:
|
|
Disable COW on journal files, as that is naturally leading to a lot
|
|
of unwanted fragmentation on btrfs.
|
|
No word on compression…
