Re: Updated FAQ page.

Perhaps , an entry about µSD selection/budgeting? There is a large difference in price between speed classes 4 and 10. I think there is a noticeable difference in the performance of a Pi between 10/UI and 10/UIII. When I started w/ the Pi I imagined class 4 would simply not work (e.g. timeout at bo...

Re: Looking for NFS tutorial

I think Arch has a good documentation. Their system uses systemd like Raspbian so it might be worth a look.
https://wiki.archlinux.org/index.php/NFS

Debian/Raspbian uses /etc/defaults for some user settings while Arch relies on /etc alone, but besides that the page should apply.

Re: Updated FAQ page.

I like it! I found the doc an interesting read, although I'm not an absolute beginner.

I've noticed in the "Power requirements" section:
- An extra tab in the last table (real-world power consumption figures)
- Pi 3B+ seems to be missing from the section.

Re: eth0 + wlan0 on jessie

You could try a variant of the eth/wifi bonding setup I described back in Jessie days. I ran 2 configs, one with static IP, the other with DHCP. The DHCP one was trickier and involved running a custom ifplugd process which might be of interest if you're not interested in bonding. https://www.raspber...

Re: Move Pi home from SD card to a HDD

I think you can get away with the disk size and terrible extended partitions constraints by using a hybrid partition table, holding MBR and GPT at the same time.

Does this Pi do anything special? Is there enough free space on the SD? What type of PSU are you using?

Re: TCP Fragmentation not working

I see a lot of DF (Don't Fragment) flags in there, and assumption of an MTU of 1500 (MSS 1460). Do you block pings at the router or Pi? This breaks PMTU discovery. To stop sending DFs, you can change net.ipv4.ip_no_pmtu_disc value to 1 in sysctl. I would also try reducing the MTU on the interface in...

Re: Node red persistent data json file keeps disappearing

In agreement with Heater. To improve data safety, you could: a. keep the data on a separate partition, that gets mounted before updates and dismounted after updates. Use the "sync" mount option. b. use 2 partitions and do everything twice, sequentially. In case of mishap you should still have a (pos...

Yes, that link points to an old, dead project, and if you read the scripts you'll see they won't work at all with Raspbian.

Consider reinstalling a fresh copy of Raspbian and reading the official AP setup documentation:

Re: FSTAB to automount NFS Share - No go... any ideas?? update: sudo mount -a WILL mount the FSTAB

Systemd reads fstab at boot and generates mount "units" that are all run in parallel. Which, not unexpectedly, causes issues.
You'll have to use systemd's x-systemd-automount option (and others) to mount that share.

I've never used pi-gen but I think target image partitioning happens here.
I suppose you'd also need a custom stage to generate a separate $DATA_DIR in order to populate that partition.
