Problems to PXE boot TinyCore
« on: March 30, 2020, 02:23:28 AM »
hello,
i have a PXE-Server project, where a pxe-client can boot into different linux distributions.
for TinyCore. i want to have at least the same behavior as when booting the ISO from a physical CD/DVD/USB.
i made TinyCore mostly working to boot into its X desktop.
but now, i have the problem that i can't install any apps. the application tries to find the fastest mirror, but because of the /mnt/nfs/cde folder is readonly.
booting TC from CD/DVD i can install apps temporary but not when i boot TC via pxe booting.

i tried different boot options, but no combinations made it working like as booting from the ISO file.
the best i could archive is with the following options:
Code: [Select]
LABEL tinycore-x64
  MENU LABEL tiny core x64
  KERNEL http://192.168.1.1/srv/nfs/tinycore-x64/boot/vmlinuz64
  INITRD http://192.168.1.1/srv/nfs/tinycore-x64/boot/corepure64.gz
  APPEND nfsmount=192.168.1.1:srv/nfs/tinycore-x64 tce=/mnt/nfs/cde noswap norestore

i can not make the nfs as read-write, because it is mounted directly from an TinyCore-ISO image on the server.
when i try to PXE-boot the ISO image directly i am only able to boot into TinyCore text console, because there is no mountpoint for the ISO-image in RAM to find the additional files for the X desktop.
i have to use the nfsmount=192.168.1.1:srv/nfs/tinycore-x64 tce=/mnt/nfs/cde options, otherwise it will not find the additional files to load the X desktop.

any ides, how i can signal TinyCore to load the additional files from /mnt/nfs/cde but use the default /tmp/tce for apps installation?

Such a mode is not supported (read-only cde dir on NFS, otherwise RAM). I recommend loading the built-in extensions to RAM via any supported method (http, tftp, or packing them into an initrd).
The only barriers that can stop you are the ones you create yourself.

thank you for your hint with http.
it took me quite some time to find httplist option and what it means...
BTW: are the wiki.tinycorelinux.net pages not working? i get always an empty page, when trying to open a wiki page.

the boot parameters are now like this:
Code: [Select]
LABEL tinycore-x64
  MENU LABEL tiny core x64
  KERNEL http://192.168.1.1/srv/nfs/tinycore-x64/boot/vmlinuz64
  INITRD http://192.168.1.1/srv/nfs/tinycore-x64/boot/corepure64.gz
  APPEND httplist=192.168.1.1/srv/nfs/tinycore-x64.xbase.lst noswap norestore

and the content of tinycore-x64.xbase.lst is:
Code: [Select]
/srv/nfs/tinycore-x64/cde/optional/aterm.tcz
/srv/nfs/tinycore-x64/cde/optional/bzip2-lib.tcz
/srv/nfs/tinycore-x64/cde/optional/fltk-1.3.tcz
/srv/nfs/tinycore-x64/cde/optional/flwm.tcz
/srv/nfs/tinycore-x64/cde/optional/freetype.tcz
/srv/nfs/tinycore-x64/cde/optional/glib2.tcz
/srv/nfs/tinycore-x64/cde/optional/graphite.tcz
/srv/nfs/tinycore-x64/cde/optional/harfbuzz.tcz
/srv/nfs/tinycore-x64/cde/optional/imlib2-bin.tcz
/srv/nfs/tinycore-x64/cde/optional/imlib2.tcz
/srv/nfs/tinycore-x64/cde/optional/libffi.tcz
/srv/nfs/tinycore-x64/cde/optional/libfontenc.tcz

/srv/nfs/tinycore-x64/cde/optional/libjpeg-turbo.tcz
/srv/nfs/tinycore-x64/cde/optional/libpng.tcz
/srv/nfs/tinycore-x64/cde/optional/libSM.tcz
/srv/nfs/tinycore-x64/cde/optional/libX11.tcz
/srv/nfs/tinycore-x64/cde/optional/libXau.tcz
/srv/nfs/tinycore-x64/cde/optional/libxcb.tcz
/srv/nfs/tinycore-x64/cde/optional/libXdmcp.tcz
/srv/nfs/tinycore-x64/cde/optional/libXext.tcz
/srv/nfs/tinycore-x64/cde/optional/libXfont.tcz
/srv/nfs/tinycore-x64/cde/optional/libXmu.tcz
/srv/nfs/tinycore-x64/cde/optional/libXt.tcz
/srv/nfs/tinycore-x64/cde/optional/pcre.tcz
/srv/nfs/tinycore-x64/cde/optional/wbar.tcz
/srv/nfs/tinycore-x64/cde/optional/Xfbdev.tcz
/srv/nfs/tinycore-x64/cde/optional/Xlibs.tcz
/srv/nfs/tinycore-x64/cde/optional/Xprogs.tcz

but now i get an error after moste of the packages in TC and at the end a permission denied error:
Code: [Select]
...
wbar.tcz /usr/bin/tce-load: line 147: desktop.sh: not found
wbar.tcz: OK

Xfbdev.tcz: OK
Xlibs.tcz Xlibs.tcz: OK
Xprogs.tcz Xprogs.tcz: OK
Done.
...

mv: can't rename '/tmp/.xsession': Permission denied

ok, i found out, that the missing desktop.sh is coming from Xlibs.tcz package... so i moved that package to the top of the httplist.
now all the desktop.sh errors are gone.
but i still have the Permission denied error at the end and no X/GUI is coming up.

Hi beta-tester
... BTW: are the wiki.tinycorelinux.net pages not working? i get always an empty page, when trying to open a wiki page. ...
That server hasn't been responding for a few days now:

Another member posted an alternate link for the Wiki:
