unlocking rootfs via ssh login in initramfs

You can unlock your rootfs on bootup from remote, using ssh to log in to the booting system while it's running with the initramfs mounted.

Setup

For remote unlocking to work, the following packages have to be installed before building the initramfs: dropbear busybox

The file /etc/initramfs-tools/initramfs.conf holds the configuration options used when building the initramfs. It should contain BUSYBOX=y (this is set as the default when the busybox package is installed) to have busybox installed into the initramfs, and should not contain DROPBEAR=n, which would disable installation of dropbear to initramfs. If set to DROPBEAR=y, dropbear will be installed in any case; if DROPBEAR isn't set at all, then dropbear will only be installed in case of an existing cryptroot setup.

Samsung Galaxy S10+ Bloatware list you can disable

Disclaimers:

• This won't uninstall the application -- even when the command says so. It'll simply remove it from your username, but it will still exist in your phone.
• With the list, YMMV. Some features might stop working after disabling certain apps. Feel free to disable just the ones you don't use.
• You need developer options enabled to run these commands, and a USB connection to your computer, with your computer running adb shell.
