[Bug 2084376] [NEW] [Ubuntu 24.10 Oracular; systemd-sysctl service] File /etc/sysctl.conf is not processed

[fprietog]

Public bug reported:

Problem summary:
----------------
After upgrading from Noble to Oracular the kernel parameters enclosed in the file /etc/sysctl.conf are not being loaded by systemd-sysctl service.

The problem is that Oracular systemd package
(systemd_256.5-2ubuntu3_amd64.deb) lacks the file
/etc/sysctl.d/99-sysctl.conf that is a simlink to /etc/sysctl.conf, so
that file is not processed at all.

Previous Noble package (systemd_255.4-1ubuntu8.4_amd64.deb) contains
that file (link) so it worked as expected.

Aditional info:
---------------
#lsb_release -rd
Description:	Ubuntu 24.10
Release:	24.10

# apt-cache policy systemd
