# This is primarily meant to be used by logpersist. This script is run as an init service, which
# first reads the 'last' logcat to persistent storage with `-L` then run logcat again without
# `-L` to read the current logcat buffers to persistent storage.
# init sets the umask to 077 for forked processes. logpersist needs to create files that are group
# readable. So relax the umask to only disallow group wx and world rwx.
