[RESOLVED] problem with mount in 24.04

[joneall]

I have several issues. Here is the first one. I have as usual copied in the part of /etc/fstab for my local parititions. Here it is:

$ cat fstab
# /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>
UUID=E6D2-2465 /boot/efi vfat defaults 0 2
UUID=668e8ec0-4a8c-4fec-87dd-4fb5468ab9ec / ext4 defaults 0 1
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
# added by jon
/dev/sda4 /home/jon/jon-files ext4 defaults 0 2
/dev/sdc5 /home/jon/music-mp3 ext4 defaults 0 2
/dev/sdc4 /home/jon/our-pix ext4 defaults 0 2
#/dev/sdc6 /samba-transfer ext4 defaults 0 2
UUID=42c241b1-901c-4378-9e9c-0978674716f5 /samba-transfer ext4 defaults 0 2

Then 'sudo mount' should mount all of them. Instead:

$ sudo mount

Mount on its own just lists the current mounts (BTW findmnt is better command for that). Perhaps it's mount - a you want?

As well, using the /dev names in /etc/fstab can cause trouble, as they can change. The installer uses UUIDs, but I much prefer LABELs; see the man page for fstab for an example.

Oops!. My bad. Sorry.
