This is done as the s3CredentialsFile specifies the environmentFile
for the systemd service, which can be used for more than just s3.

borg is able to process stdin during backups when backing up the special path -,
which can be very useful for backing up things that can be streamed (eg database
dumps, zfs snapshots).
This is to address a regression introduced in #131118.
When syncing the first dataset, syncoid expects that the target
dataset doesn't exist to have a clean slate to work with. So during
runtime we'll check if the target dataset does exist and if it doesn't
- delegate the permissions to the parent dataset instead.
But then, on unallow, we do the unallow on both the target and the
parent since the target dataset should have been created at this
point, so the unallow can't know which dataset that got permissions
just by which datasets exists.
I noticed this minor grammar mistake when running update.nix, and then
while grepping to find the source I noticed we had it a few times in
Nixpkgs. Just as easy to fix treewide as it was to fix the one
occurrence I noticed.
This option allows basic configuration of the compression technique
used in the backup script. Specifically it adds `none` and `zstd` as
new alternatives, keeping `gzip` as the default.
When sending or receiving datasets with the old implementation it
wouldn't matter which dataset we were sending or receiving, we would
always delegate permissions to the entire pool.
Previously, a failed backup would always overwrite ${db}.sql.gz,
because the bash `>` redirect truncates the file; even if the
backup was going to fail.
On the next run, the ${db}.prev.sql.gz backup would be
overwritten by the bad ${db}.sql.gz.
Now, if the backup fails, the ${db}.in-progress.sql.gz is in an
unknown state, but ${db}.sql.gz will not be written.
On the next run, ${db}.prev.sql.gz (our only good backup) will
not be overwritten because ${db}.sql.gz does not exist.
Or … none! Because forcing a string always results in an OnCalender=
setting, but an empty string leads to an empty value.

I require the postgresqlBackup in my borgbackup unit, so I don't
strictly need the timer and could previously set it to an empty list.
Current module add backups forever, with no way to prune old ones.
Add an option to remove backups after n full backups or after some
amount of time.
Also run duplicity cleanup to clean unused files in case some previous
backup was improperly interrupted.
As the only consequence of isSystemUser is that if the uid is null then
it's allocated below 500, if a user has uid = something below 500 then
we don't require isSystemUser to be set.
