hubertf 831546110a When switching the /etc/etc.current symlink, make it relative to /etc,
not absolute.

This affects an update with sysinst, which will try to look at
/targetroot/etc/fstab, which points to /etc/etc.whatever, which is
not there during the upgrade, and results in all (/targetroot)/etc
files getting nuked!
