System Info: OS : Gentoo Linux x86_64 Kernel : Linux 5.4.38 CPU : Intel core i7-7820HQ RAM : 16GiB CC : GCC 9.3.0This problem always happens when I install the emerge software.My ccache directory is mounted on /dev/sda2, which is a primary partition in btrfs.The corresponding directory permissions have been set./etc/fstab I posted below.
This is one of error messages:
