lbu

Manage apk overlay files on a diskless Alpine Linux system. Note: subcommands like include write to /etc, which is stored in RAM. You need to run lbu commit to save the changes. More information: https://wiki.alpinelinux.org/wiki/Alpine_local_backup.

• Commit changes to persistent storage (only files in /etc by default):

lbu {{ci|commit}}

• List files that would be saved using commit:

lbu {{st|status}}

• Display changes in tracked files that would be saved using commit:

lbu diff

• Include a specific file or directory in the apk overlay:

lbu {{add|inc|include}} {{path/to/file_or_directory}}

• Exclude a specific file or directory in /etc from the apk overlay:

lbu {{ex|exclude|delete}} {{path/to/file_or_directory}}

• Display the list of manually included/excluded files:

lbu {{inc|include|ex|exclude}} -l

• List backups (previously created overlays):

lbu {{lb|list-backup}}

• Revert to a backup overlay:

lbu revert {{overlay_filename.tar.gz}}
