I install without any problems the 1.0.9 distribution with tftpboot of May 2nd. I re-mkfs my old / partition mounted on /dev/sdb1, but decline to setup a swap partition (contains backup files). After all is installed and running properly I transfer back my files from sdb2 to sdb1, change the partition type of /dev/sdb2 back to swap, verify the partition, write it then reboot. mkswap /dev/sdb2 edit /etc/fstab by adding the swap entry at the top: /dev/sdb2 swap swap defaults 0 0 /dev/sdb1 / ext2 defaults 1 1 /dev/fd0 /mnt/floppy ext2 noauto 0 0 none /proc proc defaults 0 0 Then I try "swapon -a" I get the following error: swapon: /dev/sdb2: Invalid argument After some man reading and experimenting I use this entry which does seem to work: /dev/sdb2 swap sw defaults 0 0 swapon -a , doesn't generate any error, but my swap is not being used as reported by swapon -s or free (or top).

I am sure it's somthing obvious, but I am blind by nature ;) Thanks for all, Ed. PS: Congrat to David, Jakub, Eddie, ....etc for their excellent work!
