fscrypt setup fails on read-only filesystem

[REmerald]

From the docs it seems like ostree handles the filesystem stuff, so the issue may be relevant here.

I'm using Fedora Serecia 42 (Sway Atomic) and I can't setup the fscrypt encryption to use with systemd-homed.
I already installed fscrypt with rpm-ostree and enabled encrypt feature with tune2fs.

When trying to run sudo fscrypt setup it creates /etc/fscrypt.conf but then fails fails to create /.fscrypt: [ERROR] fscrypt setup: mkdir /.tmp4239808518: read-only file system. The number after .tmp is different each try.

Is there a way to make writable /.fscrypt directory in the same way as /etc and /var are created? (But probably first figure out way to allow fscrypt to make the temporary directory)

You probably want to put .fscrypt in `/sysroot, see also https://bootc-dev.github.io/bootc/filesystem-sysroot.html#growing-the-filesystem
