systemd 248 RC1 Released With New "System Extension Images" Concept

[pal666]

"system extension images" sounds like a decent way for distros to install custom packages without polluting root. Everything not part of the core os gets added to an extended image.

it's unclear how your idea will be less polluting if it's anyway mounted on every boot

Can't keep up with the pace of systemd development I think I am going to move slowly on BSD the majority of my computers...

keep us posted

That's precisely what fstab is for.

cmon, who needs kernel when you have emacs and can write it yourself?

[pal666]

The images can be read-only

this is wrong. the main use case is when root(i.e. /usr and/or /opt) is read-only, which precludes you from making mount points there

It helps keep user changes off of the core system. If the shit hits the fan you can just not mount the user overlay to see if the issue is user or base system. If paired with homed you could have portable home and user apps overlay that any core os could use. /etc is the tricky one.

/usr and /opt aren't places for user changes

Of course I do, to begin I'll setup a BSD server to host my BSD Blog on Gemini...

Humm no https://www.freedesktop.org/software...t.service.html

"System extension images are strictly read-only, and the host /usr/ and /opt/ hierarchies become read-only too while they are activated."

[pal666]

Humm no

well, article said "extensions could be ro". in reality "root could be ro"

This reminds me of old projects like: https://github.com/GregorR/snowflake

That used aufs, and one of the caveats to any approach using overlayfs is that you can only safely add layers on top, not remove any layers -- particularly out of order. Once you talk about more than one layer, rw mounting stops making sense anyway.
