Subject: [Qemu-devel] [PATCHv2 1/6] dump: create writable files
Date: Sun, 24 Mar 2013 18:27:16 +0100	[thread overview]
Message-ID: <1364146041-27041-2-git-send-email-rabin@rab.in> (raw)
In-Reply-To: <1364146041-27041-1-git-send-email-rabin@rab.in>

The files dump-guest-memory are created as read-only even for the owner.
This non-standard behaviour makes it annoying to deal with the dump
files (eg. rm -f is needed to delete them or saving a new dump by
overwriting the previous one is not possible).  Change the code to
generate files with write permissions set.  If someone requires
read-only files to be created, they can achieve it by setting umask.
