* Allow to specify a custom username in "pmbootstrap init"
* Build chroots have "pmos" instead of "user" as username now
* Installation user UID is 1000 now (as in all other Linux distributions)
* Adjust autologins
* postmarketos-base: enable wheel group for sudo, removed previous sudoers file
* Implement safe upgrade path:
We save the version of the work folder format now, in $WORK/version.
When this file does not exist, it defaults to 0.
In case it does not match the currently required version
(pmb.config.work_version), then ask the user if it should
automatically be upgraded.
If you really want to build busybox, I recommend turning the
"timestamp based rebuilds" feature off, otherwise it will build
for all architectures all the time whenever you change something,
even if you do not increase the version number (that's the idea
of that feature). This is, because busybox is a dependency for
basiscally everything, so it must get updated whenever you install
something, in case it was out of date.
It is easier to simply rename the package.
