Sudo -H now is needed to change the effective user id to 0 (i.e.
root) *and* change the home directory to root's home directory, what
was done in Panther (Mac OS X 10.3) and before inherently. In Tiger
(Mac OS X 10.4) a simple sudo leaves $HOME untouched.
In no case a 'cd $HOME' happens or happened. So a 'sudo [-H] updmap'
leaves files owned by root in one's own directory tree.
When you invoke 'sudo -H updmap-sys' or more verbosely 'sudo -H root
updmap-sys' then kpsewhich, which locates the MAP file fragments,
runs in a sub-process under the ID of root, and so $HOME in $TEXMF is
expanded to root's home directory. My private parts do not get searched.
When you invoke 'sudo updmap-sys' then kpsewhich runs in a sub-
process under the ID of root but with the old value of $HOME, and so
$HOME in $TEXMF is expanded to your own home directory. My private
parts would get searched ... but this can be dangerous when everyone
on the system would get access to the fonts only I licensed! And it
could endanger the whole system with my experimental MAP file
fragments. This does not seem to be Alex' problem, probably the MAP
file fragments are OK.
sudo -H env | grep HOME
sudo env | grep HOME
(Before I understood these mechanisms in depth I fooled updmap-sys by
linking root's ~/Library/texmf with my own, to have access to my
private MAP file fragments. And to link has in German the connotation
of fooling someone or something!)
