When you are addicted to noscripts in lfs

I use scratchpkg as a lfs package manager.

Long story short to avoid having to search manually for updates for packages on the internet I wrote a few noscripts to do it for me during a cron job.

May be "risky", probably lazy but it works for me lol.

4k laptop + Nvidia + Gnome 40 + Gestures support -> possible?

Hello, I really like the way 4K displays precise fonts on laptops. I'm thinking about buying a 4K thinkpad or dell precision, but it seems that to run 4K you'll need a Nvidia dGPU (there is no AMD option for 4K monitors in 15 inches).

I really want to use gnome 40 on Fedora and I was wondering how that would work if I have an Nvidia because apparently they don't support Wayland. I need my laptop to support gestures (something that Wayland supports better apparently) to be as close to my macbook pro as possible for a smooth transition from Mac to Linux.

Thoughts? Should I drop the 4K if I want gestures / Wayland support since 4K needs a dGPU to run well?

Does anyone know if ubuntu is planned to receive an integrated tiling option ?

I've been using i3 as my main WM and just discovered popOS and how well that works with gnome, I'm not going to change to pop just for this feature but it would be nice if the ubuntu team tried to implement it in the next LTS release as it already works out of the box for gnome.

You don't need a bootloader

Back in the day of MBR (Legacy) BIOS systems, to boot the system would execute what was in the master boot record (the first 512 bytes of the disk). Since the Linux kernel is more than 512 bytes, an intermediate program called a bootloader had to be put in the MBR instead. The most common Linux bootloader is GRUB.

Almost any computer made in the last decade now uses the UEFI standard instead of the old legacy MBR one. The UEFI standard looks for certain files in a partition called the ESP, or EFI System Partition. Since this is just a normal FAT32 partition, it can be as large as 2 terabytes. Now that it's large enough to fit the whole kernel and initramfs in, some distros mount the ESP directly to /boot so the kernel and bootloader can be stored in the same partition, making the bootloader's job easier.

Many of the kernels that distros use as their default are compiled with the EFISTUB option enabled, which means that the kernel is capable of being launched directly by the UEFI the same way as a bootloader is. Since kernels can now be launched directly by the UEFI, bootloaders aren't needed anymore since their only job is to launch the kernel and that can now be done directly by the UEFI.

Hence, if your distro kernel has EFISTUB enabled, you can forego the bootloader entirely and set a boot entry in your UEFI to directly load the kernel with a tool called efibootmgr. A good tutorial for this is located here on the arch wiki. Now that this is possible, the only reason to use a bootloader nowdays is if you're using a legacy MBR machine, or if you're using multiple kernels/operating systems and your system's bios is annoying to navigate.

Using older kernels with newer OS

I've got Ubuntu 20.04 running on a Thinkpad E490s. My top priority is battery life. Given the capacity of the battery is only 85% left, I get at least 8 hours on kernel 4.18 and only 6 .5 hours with the newer kernel 5.8. What are the pros and cons of using an older kernel with a newer OS?

Was Linus ever consider the development of an init system for Linux?

The init system is coupled with the Linux kernel in a close way, so it seems that this layer could be fitted and developed as a side project for the Linux Foundation.

Was this option consider in any time? Maybe before systemd?

iptables masquerade being affected by router?

I have 2 identical servers in a data center. Same hardware, same OS (debian buster) and both running the same configuration from saltstack.

I have the same iptables masquerade rule set up on each to route out traffic for KVM guests running on a private address space.

On one server it works great, on another i get the Redirect Host Next Hop info and the gateway fails.

The difference between the 2 servers is that they are on a different subnet, and the non-working setup is on a VLAN.

Is there any possibility that the network upstream from my server is breaking this somehow?
