    The point of use flags is to make it so if you don’t want to print, every package that would otherwise pull in CUPS as a dependency can be compiled without it. Stuff like that.

    Gentoo also has a good system for handling multiple concurrent installs of different versions of some packages, e.g python.

    If there’s software you want to install from source that uses automake it’s pretty simple to build your own package for it.

    Very much a system for doing things your way, and a good way to learn linux IMO. To that end, no there is no installer, but the process is not that complex. Boot a live USB, partition and format a drive, download and extract a base system, install a kernel (there is a fits-most-needs one available now), install a bootloader. Reboot into your new system and continue installing what you need from there.






  • No problem! To expand further, I am 99% certain it would be perfectly viable to have a single disk volume group and just take advantage of LVM’s ability to create, resize and delete virtual partitions on the fly. I think you could also put all your disks into a single volume group, then ask it to not spread your logical volumes across multiple disks, if you wanted to. Could get a bit fiddly though.


  • You are correct, LVM combines 1 or more disks into 1 or more storage pools that can then be allocated out to logical volumes as needed.

    If you just up and pull a disk from a pool (volume group), you’re gonna have a bad time. You can, however, migrate the “extents” allocated to that physical disk to another in order to replace the disk, and your logical volumes can be set up with RAID-like redundancy. There’s a lot of options on how to manage it.






  • No problem. The one I used is an ESP32 DevKitC, and you can find info about it on Espressif’s site, or just google the pinout diagram. For basic tasks it should be all you need since it has lots of binary pins, two ADC channels, two DAC channels, realtime clock, special pins for waking it from deep sleep, two I2C, etc. Though if you want to do video input you probably want something else, I’m learning.

    Anyway, if you can spare the money to get one just to toy with I’d definitely recommend it.


  • Okay so that is an issue with the ESP32, sure. There are a lot of variants.

    So from what I can tell, the ESP32 is the SoC chip and what you usually get is a dev board which has that plus a bunch of power regulation bits, a USB connector and UART so you can easily program it, etc. That part varies mostly by pinout. I.e. Same features, different pin location.

    There are also variants of the chip, but those are usually more costly and will be named things like ESP32-S2.

    Every one I’ve seen can run off 5v or 3.3v and uses the latter for logic, so if you got yourself an arduino kit and then just bought an ESP32 dev board it would almost certainly work with whatever is in the kit. Both are microcontrollers, not microprocessors, so they tend not to have OSes or screens.
