kernel: 5.0.7-arch1-1-ARCH Is this a known oddity? I tried to mount a partition today that has the gpt label and partlabel of "backups" to /mnt/backups. The syscall succeeds but in reality, it silently failed. dmesg reports the filesystem was mounted. mount("/dev/sdc3", "/mnt/backups", "ext4", 0, NULL) = 0 [...] [259524.127545] EXT4-fs (sdc3): mounted filesystem with ordered data mode. Opts: (null) It isn't actually mounted nor is there any mount data reflected anywhere in /proc or /sys for it. If the mount point is named differently, it succeeds. └─> ls -ald /mnt/backups drwxr-xr-x 2 root root 4096 Apr 18 10:41 /mnt/backups └─> mv /mnt/backups /mnt/backitup └─> mount /dev/sdc3 /mnt/backtitup └─> df|grep backit /dev/sdc3 3.8T 68M 3.6T 1% /mnt/backitup
