Apparently something in grub-installer must then be doing a write while the filesystem is frozen. I don't know for sure what it is; I suspect it may be more than one thing. One place that seems likely to write and block is the redirection of $grub_shell to $log_file. Since removing that one doesn't fix it, I'm left assuming that running $grub_shell itself somehow causes a write, and thus a freeze. Maybe getting strace on there and stracing it would help. -- see shy jo
