# /etc/tmpreaper.conf, default 7 days), protecting the .X, .ICE, .iroha and
|
|
# .ki2 files; but removing symlinks. For directories not the access time, but
|
|
# the modification time is used (--mtime-dir), as reading a directory to check
|
|
# the contents will update the access time!

# In the default, /tmp/. is used, not the plain /tmp you might expect, as this

|
|
# Note that the sockets are safe even without the `--protect', unless `--all'
|
|
# is given, and the `.X*-lock' files would be safe also, as long as they have
|
|
# no write permissions, so this particular protect is mainly illustrative, and
|
|
# redundant. For best results, don't try to get fancy with the moustache
|
|
# expansions. KISS. Always --test your protect patterns.
