Michael,
Your code above will not find the same files as what's currently in
/etc/profile. The correct code (with no subshells) is included below.
# Run all of the profile.d scripts
# Note that these are supplied by separate packages
while read f; do
if [ -f "$f" ]; then
. "$f"
fi
done << EOF
`/bin/find /etc/profile.d -iname '*.sh' -type f`
EOF
Hope this helps,
Igor
P.S. While investigating this, I found that /etc/profile.d/mc.sh uses the
'alias' command which /bin/sh doesn't recognize. Pavel, please take note.
