General TC Talk / Re: Bulding the kernel from source and making an ISO?

« Last post by Juanito on February 28, 2026, 06:37:06 AM »

You don't particularly need to rename bzImage to vmlinuz as long as your boot loader references bzImage.

To unpack modules.gz:

Code: [Select]

cp modules.gz /tmp
cd /tmp
mkdir extract
cd extract
zcat /tmp/modules.gz | sudo cpio -i -H newc -d
replace the modules under /tmp/extract/lib/modules with your newly compiled modules and add the additional ones

Move your original modules.gz from /tmp to a safe place

Pack things up again:

Code: [Select]

find | sudo cpio -o -H newc | gzip -2 > ../modules.gz
cd /tmp
advdef -z4 modules.gz

To replace the existing modules.

And just to double check, I can rename bzImage to vmlinuz (It's not vmlinux that needs to be renamed to just replace it with a z.)
I'll try and just use the same folders that exist in modules.gz matching the style for 9pnet_virtio.ko.gz

Hmm surely I'm doing something wrong yet. It'll boot to menu, but then kernel panics
Not syncing: VFS: unable to mount root fs on unknown-block(2,0)

Trying to mimic the testISO... I must have something wrong, since the testISO boots up fine.

Edit: I think I've got the compressing part of things wrong.
Using core.gz as provided under distribution files works.

If I uncompress core.gz and recompress it with sudo tar -zcvf
It'll panic. If I don't use sudo then the tar command mentions at the end
Tar: exiting with failure status due to previous errors, but nothing stands out as an error.

TCE Q&A Forum / Re: TCL and LXC

« Last post by mocore on February 28, 2026, 04:58:39 AM »

wrt tcl + lxc

+
LXD container image for TCL @ https://forum.tinycorelinux.net/index.php/topic,24369.0.html

apparently "LXD is the new LXC experience." according to https://discuss.linuxcontainers.org/t/comparing-lxd-vs-lxc/24

as this question wet unanswered and i happen to be looking into this
 ill borrow this topic

open wrt has a guide to "installing" wrt as lxc
https://openwrt.org/docs/guide-user/virtualization/lxc#via_rootfs_extraction

which has demystified a little the methods used to create lxc

rootfs is copy into .local/share/lxc/<vm-name>/rootfs
modules are shared with host

so it would appear using tc with lxc (or lxd??) is not *officially*  supported ?!

... because it would require "scatter / hybrid" install

meaning installing packages in the container would brake many of tce extension  assumptions and not work.. ( with out modification to tce install script or extension install script)

+ https://superuser.com/questions/1192947/tinycore-non-frugal-install-of-tinycore-linux

which *afaik appears to be the antithesis of the core frugal install deign
as mentioned in "Core Concepts" & illustrated in diagram of the Tiny Core file architecture @ http://tinycorelinux.net/architecture.html

... though i might be wrong ?? ... if so plz add corrections / perspectives..

@* any thoughts? ..

So what files do I need exactly? I've got a bunch of folders, arch block certs, etc.

What files do you need exactly for what?

To compile a kernel on tinycore?
To replace the existing modules in modules.gz?
To create a bootable tinycore iso?

Core is comprised of rootfs.gz, modules.gz and vmlinuz (core.gz = rootfs.gz + modules.gz)

Ah that's good info.
I found an old guide.
https://wiki.tinycorelinux.net/doku.php?id=wiki:custom_kernel

Anywho I've got a native tinycore running off a liveUSB flashed with RUFUS.
I learned my BIOS has an option for changing USB to legacy boot.

So what files do I need exactly? I've got a bunch of folders, arch block certs, etc.

fascinating commentary on a tour of the Torness Nuclear Power Station

as an aside, generally speaking, i am against any technology that leaves deadly waste products that have a half-life in the tens-of-thousands of years...smh...

and along that line of thought i remember reading something regarding deep geological repositories quite some years ago(and found it educational but not thoroughly satisfying with respect to longterm planetary safety/security)

a humble thought.

can we move this thread to "General TC Talk" and make it a sticky(pinned to stay visible at the top)?

as always, huge kudos to everyone here for making this community(and TCL) such a pleasure to enjoy!

also i concur with @GNUser rant in reply number 32:

General TC Talk / Re: Password

Hi patrikg,

Thanks again for the help, I've had a bit of a breakthrough!

I was able to get a WinXP executable called "PSCP.exe" (which I think is based on, or uses PUTTY behind the scenes) to work, just had to create the ssh config files ahead of time, start up openssh on TC 3.8.4, with a copy of "PSCP.exe" in a directory on an external hard drive, can type the usual;

Code: [Select]

pscp tc@172.16.1.98:/home/tc/data/* .

To copy the contents of the data folder on the CF card into the directory from which the PSCP.exe command was executed, somehow the PSCP.exe program deals with the
key issue, just allows me to accept the key from TC, and can continue on.

I got this "PSCP.exe" executable with a BeagleBone Black based data acqusition system, which is used to transfer data to/from the BBB.

With that, I was getting about 5-7 MB/sec over the 100 MBit ethernet port (onto an NTFS formatted external HD), but I noticed my "go-to" 64 GB FAT32 formatted pen drive was still stuck at around 1 MB/sec, which is also what I was getting with it when it was connected to the VortexDX3 USB ports as well, so that pen drive itself seemed to be the issue actually.

So, I tried some other pen drives connected direct to the USB 2.0 ports on the VortexDX3 and my goodness, what a difference!, can't believe it!, my 4 GB Cactus pen drive (ext4) was seeing almost 40 MB/sec and another mini 128 GB FAT32 formatted pen drive was getting 20 MB/sec!!, wow.

So all my problems with slow data transfers before was just due to using a low quality pen drive it seems!, wow, never expected that there could be such a difference.

Now that I know that the USB2.0 ports can indeed work pretty fast as long as you have a decent pen drive, this takes the heat off scp, etc., but at least I do have a viable "plan-B" with the WinXP laptop running "PSCP.exe" to transfer data onto an external HD, that works pretty well too but is a bit slower at 5 MB/sec.

Thanks again for the help,

David
