Each time an ordinary user logs in, there is an error
message that /etc/profile.d/alias.sh cannot be found.
This is for a new 6.1 installation with all packages
I can't reproduce this here. What does your /etc/profile and
/etc/bashrc look like?
FWIW, on a full install here, I can't find any references
to alias.sh - do you have any other packages installed?
