Description Scott Anderson 2004-02-11 20:50:15 UTC

While attempting an upgrade (using '/stand/sysinstall installUpgrade') I
ran into a problem where files are copied, hit a recursive loop and
potentially continue being copied until the partition is full.

When upgrading via sysinstall, the user (admin) is prompted for a location
to backup /etc, if the user backs this up in the /root tree, this problem
will be encountered.  Selecting /root doesn't seem like a bad place, and
the user isn't warned the next automatic step is that /root will be backed
up into the backup of /etc (thus creating the loop).  

A simple prompt not to backup /etc into the /root tree would suffice, or
preventing this in the script might be helpful.

How-To-Repeat: '/stand/sysinstall installUpgrade'
Choose to backup /etc into /root (/root/backup/etc or some such)

Watch it take a long,long time to backup, wonder what is going on,go have
a look in /root/backup/etc and find the huge recursive copy happening
(/root/backup/etc/root/backup/etc/root/backup/etc...). :)
