In live CD (pfix=ram) "su spot" working properly.666philb wrote: su spot is working for me in both PAE and noPAE, do you get the same if you boot live?
I have delimited the problem was in one of my customizations, using "unsquashfs -d / -f some.sfs" seems affects the properties of some directory (although I see I have permissions similar to the situation in live cd).
Thank you for your attention and sorry for any inconvenience.
