looks at a root dir and then applies vpick on various dirs/images to pick a

root tree, a /usr/ tree, a /home/, a /srv/, a /var/ tree and so on. Dirs

creating versions like these automatically).

RootImage=/RootDirectory=/--image=/--directory= implement this. Idea:

directories ending in ".v/" indicate a directory with versioned resources in

them. Versioned resources inside a .v dir are always named in the pattern

<prefix>_<version>[+<tries-left>[-<tries-done>]].<suffix>

apply the logic, moving the switch root logic there.

* maybe add a tool inspired by the GPT auto discovery spec that runs in the
|
|
||||||
initrd and rearranges the rootfs hierarchy via bind mounts, if
|
|
||||||
enabled. Specifically in some top-level dir /@auto/ it will look for
|
|
||||||
dirs/symlinks/subvolumes that are named after their purpose, and optionally
|
|
||||||
encode a version as well as assessment counters, and then mount them into the
|
|
||||||
file system tree to boot into, similar to how we do that for the gpt auto
|
|
||||||
logic. Maybe then bind mount the original root into /.superior or something
|
|
||||||
like that (so that update tools can look there). Further discussion in this
|
|
||||||
thread:
|
|
||||||
https://lists.freedesktop.org/archives/systemd-devel/2021-November/047059.html
|
|
||||||
The GPT dissection logic should automatically enable this tool whenever we
|
|
||||||
detect a specially marked root fs (i.e introduce a new generic root gpt type
|
|
||||||
for this, that is arch independent). The also implement this in the image
|
|
||||||
dissection logic, so that nspawn/RootImage= and so on grok it. Maybe make
|
|
||||||
generic enough so that it can also work for ostrees arrangements.
|
|
||||||
|
|
||||||
* if a path ending in ".auto.d/" is set for RootDirectory=/RootImage= then do a
|
|
||||||
strverscmp() of everything inside that dir and use that. i.e. implement very
|
|
||||||
simple version control. Also use this in systemd-nspawn --image= and so on.
