usr-local.mount removed in SteamOS 3.5 (Error when enabling service)

[sonofevil]

So I just upgraded my SteamOS to 3.5 (Preview) and then tried to install rwfus:

(130)(deck@steamdeck rwfus)$ ./rwfus -iI

Looks like usr-local.mount no longer exists in 3.5, but usr-lib-debug.mount does which has the same target (/dev/null).

@sonofevil This is a known issue, and was fixed in 0.5.0 preview. Installing 0.5.0 preview will automatically migrate your Rwfus config.

As for usr-local.mount, that's a big shame. I wasn't aware of that change (I don't actually use Rwfus -I any more—I will be writing a test for that.) If it prevents Rwfus from starting, you can remove it from Restart_Units in /etc/opt/rwfus.conf

[sonofevil]

Ahh alright.

Yeah 0.5.0 installs just fine. Thanks.
