BcalcOS includes a couple of small maintenance tools designed to handle routine system upkeep without requiring you to think about it.
apt-updates-notify
apt-updates-notify checks for available system updates and notifies you when updates are available.
When you receive a notification, you can update the system using the normal BcalcOS APT package update process.
weekly-fstrim
weekly-fstrim performs routine TRIM maintenance on supported solid-state drives (SSDs). TRIM helps an SSD manage unused blocks and maintain performance over time.
BcalcOS runs this maintenance automatically on a weekly schedule so there is normally nothing you need to do.
