Fun times, you forget one important detail, the JS code filters mount points (loopback, flatpak, and? tmpfs?) |
use `mount.total` and `mount.used` from internal metrics instead of parsing `df` output.

Wouldn't it be nicer to properly decompose this
mounts = open('/proc/mounts').read()
fs_spec, fs_file, fs_vfstype, fs_mntopts, *_rest = mounts.splitlines()[0].split()Not sure if one can remove *_rest, field definitions comes from https://man.archlinux.org/man/fstab.5

What about:
tmpfs /run/credentials/systemd-journald.service tmpfs ro,nosuid,nodev,noexec,relatime,nosymfollow,size=1024k
Mount point exists, but we likely don't want it.
