Oh, yes. There are many industrial settings in which toolchains are set for systems provided to customers, and those systems don't get a full software revamp for a decade if not much more than that.
- arp242 6y agoYeah, I worked in a few settings like this; but in those cases (very) old "LTS" kernel versions were used as well, so in my (limited) experience very old toolchains tends to be tied to very old, well, everything (including kernel).
- cestith 6y agoRHEL and CentOS 7 are using kernel 3.10.x even in 7.9 OS versions. That is, that's the nominal version that's distributed by the system and has all sorts of backported patches, especially but not exclusively for bugs with CVEs. For example, 3.10.0-1160.11.1.el7 is relatively recent, being updated 30 November 2020. Yeah, it's possible to download any version of the kernel sources and build it, but the chances of having a system that boots into a 5.x.x kernel under RHEL or CentOS is pretty small.
