Persistent naming installation option in Slackware 15?

wirelessmc · 03-09-2019, 10:19 AM

I realize this might add a little weight to the super versatile and light Slackware installation script - but - including Persistent Naming options for both booting (lilo/elilo) and fstab configuration at installation would be such a welcome enhancement. At least the addition of the UUID option (default in other distributions) in place of device names would be a great in lieu of the post installation currently required:

Has the Slackware team given this any consideration? If not I guess we are stuck with the post installation blues. At least the (above) is very good documentation.

Personally, I value the old naming practice. I put thought into choosing disk partitions and sizes. Why hide them behind unintelligible UUIDs? The multiple disks that make UUIDs necessary are not a problem for the ordinary mortal.

First, you do not need to hide anything. Here:

Code:

didier[~]$ cat /etc/fstab
# Initially /dev/sdb4
UUID=0e0b462b-0a8f-49bc-ae98-6395ce3361a8 / ext4 defaults 1 1
# Initially /dev/sda3
UUID=53ea8679-197e-437c-bdcb-61c55c509a2f /storage ext4 defaults 1 2
# Initially /dev/sdb2
UUID=446e4302-60ee-4bb8-b404-b06ef1a76057 /old ext4 defaults 1 2
# Initially /dev/sdb3
UUID=b8d9d6ba-f993-466a-a243-04b63156485b /slint64 ext4 defaults 1 2
# Initially /dev/sdc2
UUID=47af727a-ecc4-4241-b5e0-c121302d8197 /data ext4 defaults 1 2
# Initially /dev/sdb1
UUID=60CA-18FA /boot/efi vfat defaults 1 0
#/dev/cdrom      /mnt/cdrom       auto        noauto,owner,ro,comment=x-gvfs-show 0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
tmpfs            /dev/shm         tmpfs       nosuid,nodev,noexec 0   0
didier[~]$

Then, you miss the point: UUID helps especially when you are using removable devices, of which the name as /dev/something can change in several circumstances. Let's assume you have an USB stick or an USB attached drive and give just two examples.

If you plug another removable device as well as this one the name can change.
If you plug it in in another machine, the name can change.

@Didier: Your fstab is fine for fixed disks, although with that there, your uuids are unnecessary. That does nothing for usb keys, but I'd better shut up and not hijack @wirelessmc's thread.
