Subject: Fix logread file logging
X-Git-Url: https://git.archive.openwrt.org/?p=project%2Fprocd.git;a=commitdiff_plain;h=84c114b0756eaff7caf2693c61bdc307a080558c

Fix logread file logging

This patch fixes logread and now appends to files instead of writting to the beginning the specified logfile. It also sets the access rights to 0600.
