Beginners • Re: How to rename root partition on Rpi5

Code:

function getrootname() {    # returns a string for the device name                                                                                                                                    local rootfs=$(findmnt -n -o SOURCE /)    echo $rootfs    return    # To get the system disk instead of the root device, you can do something like this (remove the `return` above of course)                                                 [[ "$rootfs" =~ "mmcblk" ]] && sd=${rootfs%p2}    [[ "$rootfs" =~ "/dev/sd" ]] && sd=${rootfs%2}    [[ "$rootfs" =~ "nvme0n" ]] && sd=${rootfs%p2}    echo $sd}Thanks for that, rpdom. Always better to use a supported function than parsing the data yourself.
