This isn't as secure as checking the package signature would be _if_ you previously had our package signing public key, but on another distro you probably don't have that yet, so checking the digest against its copy obtained from this separate website is a best-effort measure.
Install the package with `rpm -U --nodeps`. The `--nodeps` option is needed to bypass the dependency check on our `rocky-release` package. In essense, you're manually confirming to `rpm` that you're installing on a compatible distro.
You'll normally install packages from the mirrors, which should just work. However, if there's any issue with the mirrors and you uncomment our `baseurl` line instead, then on non-Rocky you'll need to use `DNF_VAR_sigcontentdir=/pub/sig dnf` in place of simply `dnf`.

#### Known-effective vulnerability mitigations and fixes
`2.34-60.el9_2.security.0.2` included mitigations sufficient to avoid security exposure of [CVE-2023-4911](../issues/CVE-2023-4911.md) and a backport of upstream glibc fix of [CVE-2023-4527](https://www.openwall.com/lists/oss-security/2023/09/25/1) that was not yet in upstream EL. In the update to `2.34-60.7.el9_2.security.0.3`, we retained the mitigations while rebasing on upstream EL's package with upstream fixes for these vulnerabilities (and more).

In general, inclusion of additional security fixes will be "reverted" if and when those get included in upstream EL packages that we rebase our changes on.

### Usage in Rocky Linux
Due to EL's kABI stability and the `weak-modules` mechanism, which this package uses, the same binary package of LKRG works across different kernel revisions/builds within the same EL minor release (e.g., 9.2). Once there's a new minor release (e.g., 9.2 is upgraded to 9.3), we'll provide a new build of LKRG accordingly.

### Testing and recovery
Although the current package passed our own testing (on 8.8 and 9.2), we recommend that you only enable LKRG to start on system bootup after you've tested it for a while to ensure its compatibility with your system. If you nevertheless run into a boot time issue with LKRG later, you can disable it with the `nolkrg` kernel command-line option.
