Newbie first comments on installing piCore-8.0
« on: November 25, 2016, 06:59:49 AM »
Hello ,I am new to PiCore so please forgive me if I am doing something wrong.

Firstly let me say that it is a really great system, excellent for standalone embedded hardware. Many thanks to all involved in putting it together.

I will just report a few minor teething problems I have encountered running on an old Pi model B+.

I downloaded and installed piCore-8.0.img and it boots just fine with no apparent errors.

To get to know and understand the system I edited the boot flags and removed quiet, added showapps and pause. Rebooting now gives an error while loading gcc_libs "mount: bad option, bad superblock on /dev/loop12, missing codepage, or helper program, or other error."
I found that the md5 for gcc_libs.tcz was incorrect. I redownloaded piCore-8.0.img checked the md5, and wrote to anther SDCard using Win32DiskImager, but the same issue was there. I fixed it by deleting gcc_libs* and using tce-load to reinstall it.
_________________________________________________

I next touched copy2fs.flg and rebooted. It now gives an error for each package
"package rm: applet not found"
I have tracked this down to tce-bootload line 133 "os.system(sudo busybox.suid rm -r -f......". My fix has been to just remove ".suid" and remastered the core.gz. However I am not sure on the correct use of the SUID bit and is it needed after sudo so may have messed this up.
Anyway I now get a clean boot without any error messages.
_________________________________________________

I notice that during each boot considerable time (>20secs) is taken rebuilding the rsa keys, immediately followed by a restore and overwrites them.
Would it be better if new keys were rebuild only if norestore is specified or the backup file does not exist? But I am not sure that my sh skills are good enough.
_________________________________________________

My next task will be to install and setup Samba, I am not clear what the recommended way to start daemons, do I just add a line to bootlocal.sh?
_________________________________________________

Anyway an impressive system. Thanks.

Tim

openssh.tcz updated in the repo, please update.

Very many thanks for the very fast response.

That has certainly speeded up the boot time. However does it rebuild the keys on a new install?

I think that I have achieved my objective that is to just use the keys if they have been restored from mydata.tgz, but if not generate them.

I think using tce.installed/openssh and /opt/bootsync.sh I have achieved that.

Tim.

no need to do that, openssh has been updated to do that for you.

Bela, I tested the latest openssh everyway I can think of, and it works fine now.

Apologies and many thanks for your patience and help.

I have just done a clean start on a new card and with the new openssh all works fine.

All part of the learning curve...
