If you want help you must provide specific version and md5sum of the iso your having problems with.
Use mount with -v switch for verbose error output.
Provide terminal commands and verbose error messages.
Dmesg and /var/log/messages sometimes will provide valuable troubleshooting info as well.
I only use 5.0 32-bit rolling core version.
Slitaz 5.0 nfs client mounts to nfs-server as expected.
Test iso I burned to cdrw and booted on generic desktop:
58fa91b09ae066ac3b0827509f8eeca8 slitaz-rolling-core.iso
Command slitaz
provides info on running slitaz:
