Subject: sticky permissions of block devices
Date: Sun, 29 Nov 2009 19:08:15 +0000 [thread overview]
Message-ID: <200911292008.15575.zzam@gentoo.org> (raw)
Hi there!
Newer udev has an ugly behaviour regarding block devices.
Chown a blockdevice to some user and open it once.
udev will trigger a change event and reset the permissions back to root:disk.
The fastest solution I can propose is to restrict permission setting to
ACTION="add", but is that a good choice?
The use-case I had was to allow a user to access /dev/sda for running qemu.
Regards
Matthias
