I do know that the Linux distributions which focus on smallness usually find themselves only in niche roles because they don't have all the bells and whistles someone expected from a larger version. They then find themselves fighting off an existing base of *BSD systems which have been in that small/tidy base for decades. Back to technical terms.. the vast amount of space being used on a /boot partition is the initial ram disks which contain mostly user space tools. In a 'weird' way you could say you are seeing a 'micro-kernel' approach where various things which would have been in the kernel decades ago are pushed off to user-space.. however because the system needs those to be up very early (aka why they were in the kernel long ago) you push it into the initial ram disk. So the old school Unix people can say that Linux distributions are doing Unix kernel space wrong, and the old school micro-kernel people can say we are doing Micro-kernels wrong. Or they can say we are doing it right.. because it got moved out of the kernel to make sure the kernel only does specific things versus a MULTIX way.. and the microkernel people get to see what user space utilities ..

I first installed Linux on a 386SX (16MHz IIRC) system with a pair of 20MB hard drives and 2MB RAM... it took a little while. :) I think we ended up just using one drive for the root filesystem and the other for swap! This was probably 1992 or 1993, can't remember.

Anyway, for the sake of precision. I made the same installation with RHEL8 (anaconda 29.19 vs 29.24 on F29). The results are same! Following "logvol" stanza "--percent=100 --grow" works for EL7 but not for EL8. While doing this again I found a solution; "--size=SIZE --grow" as options with an arbitrary SIZE will grow the LV to the size of the free VG size. -- LF ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

That sounds reasonable but it doesn't help (tested up to 3GB for boot). The point is, that with fixed sizes everything works (even with 3GB root, 512MB boot, 768 RAM). The anaconda text-installation process passes without any problems. Only when "--grow" option comes in the problem appears. And this only for Fedora29, a C7 installation works fine (dynamically expands to the boundaries of the disk). Looking into the docs doesn't show any modifications: https://pykickstart.readthedocs.io/en/latest/kickstart-docs.html#chapter-3-kickstart-commands-in-red-hat-enterprise-linux It seems that with every new major release the headaches starts again :-(. While writing I did a new installation; the grow option for the "part" command seems to work. The VG expands to the disk boundaries. So, the problem gets more located around the "logvol" command ... -- LF ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
