Subject: [Buildroot] Strange behavior with shell redirection
Date: Fri, 18 Dec 2009 19:03:54 +0100	[thread overview]
Message-ID: <20091218190354.5302ccfe@surf> (raw)

Hello,

Le Fri, 18 Dec 2009 13:10:41 +0100,
Cyril HAENEL <chaenel@free.fr> a ?crit :

> ./potentiostatApplication >> /var/log/potentiostat

In the default Buildroot target skeleton, /var/log is a symbolic link
to /tmp, and /tmp is mounted as a tmpfs (the contents of the filesystem
are stored into memory).

So with the default Buildroot configuration, the contents of /var/log
(and many other /var directories) are lost when you reboot.

Cheers,

Thomas
