udev-core change:
-Requires: uname(release) >= 3.13
+Requires: uname(release) >= 4.15
Is this true requirement?
I mean docs say:
"
README: say kernel 4.15 is the minimum recommended
After various long discussions
(https://lists.freedesktop.org/archives/systemd-devel/2022-March/047587.html,
https://lwn.net/Articles/889610/), there is no clear answer what
the minimum
version should be. Bumping the version above 3.15 doesn't allow us
to make any
significant simplifications (unless we went *much* higher). In
particular, even
renameat2() is not fully supported with latest kernel versions,
e.g. nfs still
doesn't have it. And the bpf stuff is optional anyway. So let's
just say that
4.15 is what we recommend, because it provides fairly complete
cgroups-v2, but
without any removals of compat in the code."
and
"+Kernel versions below 4.15 have significant gaps in
functionality and
+are not recommended for use with this version of systemd. Taint
flag
+'old-kernel' will be set. Systemd will most likely still
function, but
+upstream support and testing are limited."
so looks like it should work on older kernels but there could be problems.
Is there really some problem with udev-core that needs forcing >= 4.15?
(I'm still using vserver 4.9 kernels)
