WIP: This is mostly to fix various problems encountered on SF CF Solaris
servers for the install target only. This did not handle /[^C]*, test -e, not
quoting within tests (ie [ `id $(USER)` = `id` ] needs quoting) in some
situations, and does not support id -u (with the id in $PATH, but there is
another...). Also, cleaned up output. Needs testing. I am unable to test the
root install stuff either. It installs now at least (not tested further).
A few other nits.
