Uart_enable overrides cmdline.txt

[aapris]

Running Sensly installer replaces boot parameters in Raspi's cmdline.txt file while installer is runningUart_enable.sh.

This is bad, because cmdline may have custom modifications and removing them may make Raspi inaccessible.

A suggestion, instead:

• parse existing cmdline parameters
• remove only known parameters which are known to cause issues
• add your own parameters
• leave other parameters untouched

echo "dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet splash plymouth.ignore-serial-consoles" >> /boot/cmdline.txt
sed -i -e '1s/^/#/' /boot/cmdline.txt

Or at least ask user before overriding cmdline, so user can manually modify parameters, if she/he wants.
