I've uploaded a test version of bash, 3.0-12, that changes the behavior of cd to use realpath() for -P, and to only check existance of the entire path (rather than all intermediates) for -L, so that you should be able to cd /a/b even in POSIX mode when /a doesn't exist but /a/b is a drive mount. This new version also implements the postinstall improvements - using a shell script to set up a batch file without regards to whether /bin/sh runs it, then using the bat file to force bash to run the real postinstall script. The postinstall script is now also run as part of /etc/profile.d, so that even if setup.exe couldn't update /bin/sh, a normal bash login might do so, hopefully reducing some of the complaints on this list about /bin/sh disappearing. Furthermore, the postinstall checks timestamps first, and won't upgrade /bin/sh if it is newer than bash. Because realpath() is buggy until 20050826 snapshot or later, and because the postinstall script changed (and 01bash.bat is the first .bat in /etc/postinstall), I marked 3.0-12 as test, and am not sending a release announcement until cygwin 1.5.19 is finalized. - -- Life is short - so eat dessert first!
