Hello,

Just wanted to share that while installing Cygwin64 on a clean PC, setup threw me the following postinstall errors:

2013/04/22 21:38:33 running: C:\Cygwin64\bin\bash.exe --norc --noprofile "/etc/postinstall/bash.sh"
ln: failed to create symbolic link `/dev/stdin': Read-only file system
ln: failed to create symbolic link `/dev/stdout': Read-only file system
ln: failed to create symbolic link `/dev/stderr': Read-only file system
ln: failed to create symbolic link `/dev/fd': Read-only file system
2013/04/22 21:38:33 abnormal exit: exit code=1

Re-running the following commands (taken from the postinstall script) from bash after having started
the actual Cygwin window, did not return any errors and did in fact create the missing symlinks:

/bin/test -h /dev/stdin  || ln -sf /proc/self/fd/0 /dev/stdin  || result=1
/bin/test -h /dev/stdout || ln -sf /proc/self/fd/1 /dev/stdout || result=1
/bin/test -h /dev/stderr || ln -sf /proc/self/fd/2 /dev/stderr || result=1
/bin/test -h /dev/fd     || ln -sf /proc/self/fd   /dev/fd     || result=1
