This is the configuration for my personal computers. See also my dotfiles for user-specific configuration. Most of the files here are probably not that useful to anybody other than me (except maybe to look at for ideas or something), but a few might be more generally useful.

Simple monitoring scripts that can be used with cron to send an email when an administrator might want to take action:

• salt/file/backup/repo/borg_require_recent_archive.py: Alerts when a Borg repository doesn't have a recent enough backup archive.
• salt/file/disk_usage/disk_usage_at_least.py: Alerts when disk usage is higher than the specified percent.
• salt/file/lost_found/monitor.sh: Alerts when lost+found has anything in it.
• salt/file/uptime/uptime_warning.py: Alerts when the system's uptime is too high (and the system should be rebooted).

salt/file/accounts/generate_lemonldap_ng_ini.py makes it possible to rotate LemonLDAP::NG's OpenID Connect keys with the Local configuration backend.

salt/file/crypto/x509/boilerplate_certificate.py provides a relatively easy way to create X.509/PKIX boilerplate around a public key, for use with out-of-band certificate provisioning. It serves the same purpose as self-signed certificates, but uses a separate CA and EE certificate to avoid some issues with self-signed certificates.

salt/file/todo/todo.py sends scheduled TODO emails. I used to use recurring calendar tasks for this purpose, but I had trouble finding CalDAV clients that supported recurring tasks well. Thunderbird was the best I found, but between https://bugzilla.mozilla.org/show_bug.cgi?id=1686466 and https://bugzilla.mozilla.org/show_bug.cgi?id=1786656 it wasn't reliable enough.

salt/file/xmpp/ejabberd_authentication.py is an ejabberd external authentication script that makes it possible to have multiple passwords per user (e.g., so a user can use a different password on each of their devices). It uses a simple configuration file in the style of passwd or shadow files
