An unofficial Debian Installer for Pinebook Pro
(01-30-2020, 12:59 PM)Der Geist der Maschine Wrote: Memory filesystem


If I recall correctly, Manjaro sets up several memory filesystems. Any thoughts on introducing memory filesystems for /tmp and friends on our Debian builds?

The plus: Less flash wear.

The minus: on a memory constrained system such as the Pinebook Pro (and in particular in combination with 64bit binaries) this might result in more paging.


Note: When I was running Manjaro for some time, emacs's cscope mode was requesting more space in /tmp than what was configured. So, with a conservative /tmp size, we may run into problems from time to time.

I've been very successful with implementing zram-swap, as outlined here zram swap support for the PBP; aka: "how to download more RAM" by  @"Arglebargle"  

On the PBP, with Bullseye at least, this is not without minor problems. It causes lsblk to hang, which interrupts common operations, like updating initramfs from apt/dpkg/etc. I worked around this by manually turning off swaps and unloading the module for these tasks.

Otherwise, zram-swap should be almost considered for default, as it addresses your concerns about solid-state storage wear and swappiness - while increasing functional RAM availability. Android has this standard for years, and little wonder, considering the target devices and their use cases.

I've run these for my PBP off of USB, SD, emmC and now NVMe. I haven't had a timeout with encrypted LUKS at boot. Are you booting from SD? Just guessing, this may be a lower-rated or "worn" SD card.
I'm using the internal eMMC exclusively

Ah. It was worth a shot. My eMMC, on two different machines, haven't had this problem. I'd still bet it's the particular chip, or partitions and formats.
If your parts/formats are standard from the debian-installer script, I'd eliminate those, as I again have two working examples - 64 and 128 Gb.
