No, this is wrong on both counts.
By convention, the home directory of the uucp login has corresponded
to the UUCP PUBDIR. Traditionally this was /usr/spool/uucppublic, and
maps to /var/spool/uucppublic these days. Thus, if I wanted to
copy a file to the public file area on machine b I would incant
uucp file b!~
and the uucico on the remote end would expand the '~' to
/usr/spool/uucppublic.
This usage predates (and probably inspired) the common behavior of
current shells handling of '~' expansion. While no modern UUCP I'm
aware of uses the value of pw->pw_dir to derive PUBDIR, POLA would
imply that the interpretation of '~uucp' should be the same for
both the uucp(1) command and for shells that do ~ expansion. Therefore
I would recommend keeping the UUCP home directory as /var/spool/uucppublic.
If you want to be paranoid you make this directory owned by root.wheel
and mode 0555 without breaking anything.
As for the `uucp' account's shell, this should be set to
/sbin/nologin. The purpose of the uucp entry in /etc/passwd is to
provide a unique runtime uid for the setuid UUCP components. Note that
there are some periodic maintenance scripts that should be run if you
actively use UUCP. These traditionally run under the `uucp' identity,
so you need to make sure that they will continue to function with
/sbin/nologin. (Which they should, otherwise they would have barfed
with uucico as the shell.) The shell for the uucp account should most
certainly NOT be uucico! And you should *never* allow remote site UUCP
logins (those that run uucico) under the `uucp' login, for obvious
security reasons. Instead, create seperate unique logins for each
remote site, just as you would for each of your shell accounts, but
set the login shell to uucico.
