Ok, Yves04 this is what I have in the file /etc/fstab after I installed version 5.0rc2 to my only partition on /dev/sda:
# /etc/fstab: Information about static filesystems.
#
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
devpts /dev/pts devpts rw,gid=5,mode=0620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
tmpfs /var/lock tmpfs defaults 0 0
/dev/cdrom /media/cdrom iso9660 user,ro,noauto 0 0
#/dev/sda3 /home ext3 defaults 0 2
#/dev/hdb1 /mnt/data btrfs defaults 0 2
#datasvr:/nfs/home /home nfs tcp,nolock 0 0
Never seen this file before but I imagine that it should be entries by default for devises like /etc/sda1, /dev/sda2 and the swap. Probably commented with the # sign at the beginning of the lines
and and when you do the installation they are uncommented or the installation added when the system boot for the first time from disk. ( Or something like that. Know Linux but not that much)). But if we don't have the documentation about how to created a swap partition we are a little bit lost. Most Linux distros created a swap partition by default for you or ask you about it. I will install again and create 2 partition; /dev/sda1 and /dev/sda2 with extension 2. The reason why ext2 is because when I used ext4 I always got an error message at boot time; "can recognize. .... something about ext4. The display ran too fast and I can hold it to see it. But it didn't look confident. Maybe there is something with that too.
Don't feel bad about your English, Mine is not that good either. My first "interpretation" about your solution was to run from the ROOT PROMPT #; mkswap /dev/sda1 and then swapon. The system when "kaput". Don't worry, I'm becoming an expert installing Slitaz 5.0-rc2 many times.
