The advice to not cache data in ARC is simply wrong--PG does not work that way, shared buffers are more special purpose. PG *expects* the majority of caching to be done by the OS file cache and is designed around that assumption.
LZ4 compression changes things with regard to record size--even with fast NVMe--using a record size that will fit multiple compressed blocks increases performance by reducing the total data written despite the partial record writes. (I have benchmarked this extensively.)
When mail dataset is created in /var/mail, the filesystem package will fail to install (as it does not expect /var/mail to be a directory, see https://archive.virtualmin.com/node/23096), so create it in /var/spool/mail instead as is usual.
Install the "python" package to get the a friendly bin/python wrapper
and install dependencies using origins rather than package names in
order to install the default flavor.
I am not sure under what circumstances this occurs, or whether it also
affects Debian Buster or Ubuntu.

Without the double quotes, the $DISK variable expands and will not
handle multi-disk correctly.

RPM will prompt to install our signing key, so no need to manually import it:
```
ZFS on Linux for EL9 - kmod 3.3 MB/s | 3.4 kB 00:00
Importing GPG key 0x9DB84141:
Userid : "OpenZFS <release@openzfs.org>"
Fingerprint: 7DC7 299D CF7C 7FD9 CD87 701B A599 FD5E 9DB8 4141
From : /etc/pki/rpm-gpg/RPM-GPG-KEY-openzfs
Is this ok [y/N]: y
```
Removing the line also gets around the problem of the key being renamed from `RPM-GPG-KEY-zfsonlinux` -> `RPM-GPG-KEY-openzfs`
Add our new key for EL9+ and Fedora 37+, and update instructions
to include EL9. Also update links for Fedora/EL to use the
new zfs-release-2-2 RPM.

Earlier we had to revert the CentOS 7 zfs-release RPM to point to the older `zfs-release.el8_6` RPM, since the newer universal RPM was encoded with zstd compression (which CentOS 7 didn't support). Since then, we've rebuilt the universal RPM with gzip, so we can use it again.
The source package is zfs-linux, not zfsutils-linux. I had this wrong
in the fix for #314.
