G'day

I've been following the recent thread Subject: Re: Debian on Pine64
H64B?

I'm looking for suggestions for a new SBC, please. Ideally something
more than 2M RAM. I see that a few a happy with Pine laptops. Does this translate to their SBC?

Thanks

Background.
I've just set up a new SDCard with raspberryOS. Set myself up as a
user, and set root passsword. When I sshfs to my laptop, the mount
point AND all subdirectories are owned exclusively buy user pi. Not
even root has access. So I'm out of raspberry as quick as possible.
I'm in the process of writing debian to a SDcard in the hope that that
will let me get on.
Some will recall the discussion around raspberry adding a MS repo to sources.list last year.

I'd suggest [1], but I'm unsure about the completeness of hardware
support of the current Debian stable.
Or [2], but given the current state of Mesa's panfrost it would be
rough, and this SBC has its share of issues with built-in USB.

But without a specific requirement probably the best way is to direct
you to the list like [3]. You can probably expect working UART, USB and Ethernet from the most of SBCs there.

IMO that's expected from fuse.

I've "installed" fresh RaspiOS recently and they're still doing it.

You'll have seen the pointer to 100+ SBCs. The problem with many of them
is that they are cut down to a price point rather than being built to a
quality standard. "Raspberry Pi-alike" GPIO pins don't transfer to automagically being able to run an add on in the same way you would on a Raspberry Pi, for example, and some manufacturers appear to produce
a large range of almost identical looking boards where you can't rely on them _actually being identical.

I'd single out Odroid as being very highly priced by comparison but
also very well built: the problem is that the boards take a while to
be fully supported on non-vendor kernel and in vanilla Debian - and by
that stage, the board may be out of production.

Pine's RockPi with 4G of memory seems to work quite well and be relatively
well supported.

Factor in cases, eMMC and so on as well, if you want them. A lot of the
boards do not hve a custom made case and some of them will be non-standard shapes/sizes.

Good to know. I haven't ventured into GPIO in the 5 years I've been

It's amazing. The boards look reasonably priced, but when you add on the necessary bits, they often get to the price of a low end laptop. I have wondered a few times why I don't move that way.

I know people who have bought (used) those
Dell/Lenovo/Supermicro Mac Mini-sized computers for that very reason:
at what price point you are using a SBC just for the sake of using a
SBC when a Mini-sized Linux-running computer would be a more capable
device at a similar price?

DRAT - I mistyped - the Rock64 and the RockPro64? - the Rock64 has 4G of
memory and a good selection of I/O, 1G Ethernet and the potential for eMMC storage. The RockPro has even more.

The other thing that's missing from the Raspberry Pi range is a good RTC
- a real time clock is not just a nice to have.

Thank you. As it happens I was looking at this the other night.

I'd suggest going for the RockPro64 instead of the Rock64.
I have (several) Rock64's and several things don't work (as well) as one would expect. Hopefully some things can still be improved over time.
Things seem better on the HW side with the RockPro64 and it's more powerful. Before buying f.e. some PCIe card, it's wise to first ask/check on the forum (f.e.) whether the device you want to buy will actually work properly. Several do, but not all of them.

And you likely also want to buy some cooling device/case for it.

So you had a problem with sshfs permissions, rather than investigate
said problem (e.g. https://unix.stackexchange.com/questions/59685/sshfs-mount-sudo-gets-permission-denied )
you chose to blame the Raspberry Pi.

And part of why I am contemplating a low end laptop. Another
consideration is that I can remove the monitor and keyboard from my
overcrowded desk.

I meant something different.
sshfs by design is a complex frontend to scp.
Regardless of which user runs sshfs on RPi (or any OS for that matter),
remote "part" of sshfs (i.e. - your laptop filesystem(s)) is limited by
which user you're using to connect it to the remote host.

For instance, a local (for RPi) root is writing to sshfs mounted on a
RPi, yet sshfs is setup like this:

sshfs user@laptop:/ /mnt

And it's expected that actual reads and writes that are happening on a
laptop are limited to whatever directories and files "user" is able to
read and write on the "laptop". And unless remote user is root, chowning
files or directories is forbidden.


If you need more complex behaviour for file sharing, I suggest you to
explore NFS. It is not that hard to learn if you limit it to sec=sys and
NFSv4.
Samba will fit this role too, but it takes somewhat strong stomach to
setup and use Samba. YMMV.

What woukd happen if I removed the 'pi' user account?

In the scenario above that would change nothing. For sshfs (or any
fuse-based filesystem for that matter) is does not really matters who
the local user is, all that matters is which user and where exactly
reads and writes are happening.

This is why I started a new thread.

Frankly, this subthread belongs to debian-user, there's nothing
ARM-specific here.
In the case of further questions regarding sshfs or network filesystems
in general I suggest you to start a new thread at debian-user.

I did "apt purge raspberrypi-sys-mods", mainly because that particular
package betrayed me in the past by introducing vscode.list. And doing it
the worst way possible - instead of providing the file as a part of the package, it was created by postinst script of raspberrypi-sys-mods.

But, discussing RaspiOS is considered off-topic and inappropriate here,
so that's my last contribution in this subthread.
