How to handle new shells in Fedora packages
As this file can be edited by sysadmins, we need to first determine if relevant lines are already in the file.
If they don't already exist then we just need to echo the shell's binary path to the file. Since Fedora 17 and later make /bin a symlink to /usr/bin we need to place both paths into the /etc/shells file. Here is an example of the scriptlet to package with shell named "foo":
%post
if [ "$1" = 1 ]; then
if [ ! -f %{_sysconfdir}/shells ] ; then
echo "%{_bindir}/foo" > %{_sysconfdir}/shells
echo "/bin/foo" >> %{_sysconfdir}/shells
else
grep -q "^%{_bindir}/foo$" %{_sysconfdir}/shells || echo "%{_bindir}/foo" >> %{_sysconfdir}/shells
grep -q "^/bin/foo$" %{_sysconfdir}/shells || echo "/bin/foo" >> %{_sysconfdir}/shells
fi
%postun
if [ "$1" = 0 ] && [ -f %{_sysconfdir}/shells ] ; then
sed -i '\!^%{_bindir}/foo$!d' %{_sysconfdir}/shells
sed -i '\!^/bin/foo$!d' %{_sysconfdir}/shells
fi
