I'm not sure about “udev”, however, there's some way to fix this. This
is in “fstab” manual:
Instead of giving the device explicitly, one may indicate the (ext2 or
xfs) filesystem that is to be mounted by its UUID or volume label (cf.
e2label(8) or xfs_admin(8)), writing LABEL=<label> or UUID=<uuid>,
e.g., ‘LABEL=Boot’ or ‘UUID=3e6be9de-8139-11d1-9106-a43f08d823a6’.
This will make the system more robust: adding or removing a SCSI disk
changes the disk device name but not the filesystem volume label.
I have tried this with a normal (not removable) disk and it worked fine
except, sadly, with FAT file-systems! (That was a long time, so it
might be fixed in newer “mount” versions. Just try it and see if it
To try this, just edit “/etc/fstab” and substitute the device name (say
“/dev/sda1”) with “LABEL=volume_name” (case sensitive, and substitute
“volume_name” with whatever you labeled your partition) and that's it.
