Where possible it is a best practise to safely check your filesystems before mounting them (especially read-write) to ensure you are not working with a corrupted (and further damaging a) filesystem.

(Re)install the filesystem tools you need

If you are following the recommendation to operate as non-root, the only thing to remember is to ‘become root’ (e.g. doas, sudo, or su) when executing the apk add commands, when following the filesystem tool install guide from the install process.

Enable localmount on default runlevel

doas rc-update add localmount default

Don’t forget to commit your changes

Otherwise they will be lost on reboot.

doas lbu commit
