UUID in fstab furing install?

Hi,

is it possible to have UUID in fstab during Slackware install, instead of /dev/sdX?

I am not sure about during the install, but after the install you should be able to drop into a shell, chroot into the new install, edit the fstab then restart.

yep. The thing is, I have an old HPE server, where during install the SSD is seen as sda and the RAID is seen as sdb. After installation, these seem to switch, so I end up with a non-working system. Many distros use UUID by default for fstab, so are there any chances we'll see this in Slackware?

That is very common behavior with Linux distros when using a USB to boot and install from. Easy enough to change after as pointed out above. As to your ? about using UUIDs in fstab, I don't know but I see it would simplify things in some cases.

The primary benefit I see is that, if you have multiple (external) partitions, it ensures that each is mounted to the same mount point on reboot.

The machine I use as a media center (that's kind of overbilling it--it's a bunch of stuff I collected on Usenet) has three external drives with four total partitions. It was helpful knowing which collection was at which mount point.

Giving each of those filesystems a label and them muonting by LABEL= is a lot more human-compatible than mounting by UUID.
