I think you can safely remove the four packages mentioned in your original post, if you do not have any hardware that requires them.

If you do need them, or if you keep them installed just in case, then you really must allow them to stay up to ...

Re: PXE boot and the pxelinux.cfg directory

PXELINUX is the name of a specific bootloader, part of the SYSLINUX family.

The closest thing to pxelinux.cfg for the standard Raspberry Pi firmware bootloader is config.txt. You cannot present the user with a boot menu, but you can do simpler things like checking GPIOs before you decide which ...

Re: Pi 5 angled USB C adapter safe?

There should be no problem here ! A Pi5 cannot use more than 5A at 5.1V = 25.5W.

The adapter claims to support 240W charging, which in the context of USB PD is 5A at 48V, so it should be okay for the current. Except that, if it adds even 0.1Ω of resistance ...

Re: Filesystem check problems with Trixie

fsck actually runs on every boot, but (unless forced) if it sees that a filesystem is marked clean, it skips most of the work.

"not clean" basically tells fsck to do the full check. The filesystem was not safely unmounted and does not have a journal, so it might be in an inconsistent state. (A ...

Can't see why not, the setting is there to be used. If the purpose is to avoid overlapping times on future boots (I have not checked), then one minute is a sensible option, and one hour is not.

Booting takes a significant fraction of a minute, but within an hour you might have started something ...

Re: Filesystem check problems with Trixie

If you shut the Pi down properly and put the SD card into another computer (without mounting it), the filesystem state should be clean.

If you check the filesystem state on the Pi itself, while it is mounted, it may not be clean. In particular, if you have removed the journal then I do not think it ...

Or if OP built Python themself in 2021, then I do not understand how they would not have used 3.9.
