Title: bootcode question
Post by: emninger on January 11, 2016, 06:42:35 PM

While i did a little check-up with Control Panel > System Stats > boot i discovered i have

Code: [Select]

BOOT_IMAGE=/tce/boot/vmlinuz
BOOT_IMAGE=/tce/boot/vmlinuz
in the end. It's redundant, isn't it? Checking my extlinux.conf, i see i have

Code: [Select]

Kernel tce/boot/vmlinuz
and at the end of the APPEND line

Code: [Select]

BOOT_IMAGE=/tce/boot/vmlinuz

Should/can i delete one? And which one, in case?

This is the culprit at the end of the append commandline

BOOT_IMAGE=/tce/boot/vmlinuz



Also I think we've mention before about the unnecessary restore= and local=  right..?

Thanks for the pointer.

restore= is unnecessary as well?
I knew for local= - but i'm afraid to ruin something (the last time a took it away many personal settings were killed; but, probably i had changed something else as well).

Footnote: A safe backup would give me a "mydata" backup which, in case of trouble i could rename and use as mydata?

Surely the book or wiki describes it better. IIRC safe backup moves mydata.tgz to mydatabk.tgz then updates mydata.tgz. If you run into trouble with mydata.tgz (corrupt or messed up settings), move or delete it, move mydatabk.tgz to mydata.tgz, reboot and all good again. Backup is just a tool, you can create your own mydata backups manually (eg. mydata.tgz.old1, mydata.tgz.old2) and restore as desired. There's also a safebackup boot code: http://distro.ibiblio.org/tinycorelinux/faq.html#bootcodes.
