# Make sure initrd-root-fs.target depends on sysroot.mount
# This seems to affect mainly ubuntu-22 where initrd-usr-fs depends on sysroot, but it has a broken link to it as sysroot.mount
# is generated under the generator.early dir but the link points to the generator dir.
# So it makes everything else a bit broken if you insert deps in the middle.
# By default other distros seem to do this as it shows on the map page https://man7.org/linux/man-pages/man7/dracut.bootup.7.html
