最近我遇到了一个问题，我必须使用 tty 将我的主目录的权限更改回我的主要用户，并且每次启动时都会发生这种情况。我不知道是什么原因导致这种情况不持久。我该如何彻底解决这个问题，并在将来避免这种烦人的解决方法？
tty中的操作顺序：
使用 UN 和 PW 登录
sudo su
(now acting as root user)
cd home/seumas/
chown seumas .
(exit tty and log in graphically)
/etc/fstab 内容
# /etc/fstab: static file system information.
# Use 'blkid' to print the universally unique identifier for a device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda2 during installation
UUID=435410b9-b4b3-4bcb-b300-8967be32612d / ext4 noatime,errors=remount-ro 0 1
# /boot/efi was on /dev/nvme0n1p2 during installation
UUID=441E-E722 /boot/efi vfat umask=0077 0 1
# /home was on /dev/sda4 during installation
UUID=1b60b312-8481-4338-bab3-ba8a572ff3e0 /home ext4 noatime,defaults 0 2
# swap was on /dev/sda3 during installation
UUID=f3e2d240-3a9c-4e0d-8a08-77704641c8a3 none swap sw 0 0
