I don’t trust any of the major phone manufacturers to update my device for an extended time. It is intrinsically against their interest to support a platform long term at the expense of a missed sale on a new device.

Not that I like Motorola, but they do offer an unlocked bootloader on most of their phones. LineageOS supports a number of them officially, which makes for a very easy install and extended support model. Not bad for a $300 phone.

Great write-up! This might help some of the bigger instances as well.

The procedure looks straight forward enough, but depends on your installation method. Documentation can be found here: https://join-lemmy.org/docs/administration/backup_and_restore.html
