"Are you assuming that the only reason people ever upgrade kernels is for new hardware drivers?"
Well If I'm running on older hardware, I know that I won't be able to use the fancy new features...
I'll take that answer as a "yes" to my question. Perhaps you do not realize some of the other nifty things that kernels do besides support hardware, especially the linux kernel? :)
If I have old hardware, do you think I do not want?:
- New advanced more robust filesystems (ext3/4, xfs, jfs, reiserfs, fuse, unionfs, brtfs, glusterfs...)
- New networking protocol support, iptables...
- Security fixes/new security models (SELinux, apparmor...)
- Improved schedulers, i/o, process, elevators...
- Improved block management features, lvm2, drbd, nbd, iscsi...
- Performance improvements (futexs, pipe io, select/poll........)
- Real time improvements, low latency...
- Containerazation support
- User api improvements .......
- General bug fixes ......
In fact, I am embarrassed to say that I probably haven't even touched the tip of the iceberg of non hardware features that someone with an old kernel might want since I am too ignorant. But, surely you should be able to realize that newer kernels in linux mean a lot more than newer hardware support!
