Hello, I use tar for backup and experienced something very strange. If you do tar c /etc|tar xf - on a debian stable (version 1.27) all symlinks in rc0.d and alternatives are fine. If you do so on debian unstable (version 1.29) you get broken symlinks in at least rc0.d. I found out if I use tar c /etc|tar xfp - it works but I am not sure if this is a bug. But I am afraid it might break some restore processes.
With kind regards, nosy
