I hope it is ok to report this here. If there is another place to report these corrections, please let me know, I could not find one.
There is a little but important typo in the Wiki article "Vu Multiboot":
https://wiki.openpli.org/Vu_Multiboot
Section at the end of the article: "Before you start"
To make this backup, you need access to the commandline, so login using SSH or telnet. Then execute the following commands:
- tar -cvzf /media/hdd/linuxrootfs1.tar.gz /linuxrootfs1 (for slot 1)
- tar -cvzf /media/hdd/linuxrootfs1.tar.gz /linuxrootfs2 (for slot 2)
- tar -cvzf /media/hdd/linuxrootfs1.tar.gz /linuxrootfs3 (for slot 3)
All three tar commands create the identical backup file and would overwrite each other.
If someone used just copy and paste that could be irritating.
