Due to a mistake of mine, i've reinstalled all my system last night, and upgraded to unstable with the last kernel for my architecture downloaded with apt (package linux-image-2.6.15-1-k7).
But I've got a....strange problem. I've put /var on a separate partition (my /etc/fstab is coming) on /dev/hdb3, but, this /var is a little strange.
While booting with the installation kernel (2.4.18, no initrd), it correctly mounts under /var, and it's populate with the lib/, log/, data/, of a normal system (and i'm posting with this kernel).
But when i'm trying the 2.6.15 kernel, the /var partition mounts correctly, but it's empty. The partition is mounted (and I manually mount/umount it, to be sure), but whatever i can do on it, when i'm go back to 2.4.18, the /var partition is in the same state than the last boot under 2.4.18.
Here's my /etc/fstab entry for this partition:
/dev/hdb3 /var reiserfs defaults 0 2
Thanks for your help, I'm getting crazy
