tmpfiles: extend "Age" to accept an "age-by" argument
For "systemd-tmpfiles --cleanup", when the "Age" parameter
is specified, the criteria for deletion is determined from
the path's last modification timestamp ("mtime"), its last
access timestamp ("atime") and its last status change
timestamp ("ctime").
For instance, if one of those paths to be cleaned up are
opened, it results in the modification of "atime", which
results file system entry to not be removed because the
default aging algorithm would skip the entry.
Add an optional "age-by" argument by extending the "Age"
parameter to restrict the clean-up for a particular type
of file timestamp, which can be specified in "tmpfiles.d"
as follows:
[age-by:]cleanup-age, where age-by is "[abcmACBM]+"
For example:
d /foo/bar - - - abM:1m -
Would clean-up any files that were not accessed and created,
or directories that were not modified less than a minute ago
in "/foo/bar".
Fixes: #17002

<para>The age of a file system entry is determined from its last

modification timestamp (mtime), its last access timestamp (atime),
|

and (except for directories) its last status change timestamp

|
||||
prevent cleanup if it is more recent than the current time minus

the age field. To restrict the deletion based on particular type
|

of file timestamps, the age-by argument can be used.</para>
|

|
||||
<para>The age-by argument, when (optionally) specified along
|
||||
with age will check if the file system entry has aged by the
|
||||
type of file timestamp(s) provided. It can be specified by
|
||||
prefixing the age argument with a set of file timestamp types
|
||||
followed by a colon character <literal>:</literal>, i.e.,
|
||||
<literal><replaceable>age-by</replaceable>:<replaceable>cleanup-age</replaceable></literal>.
|
||||
The argument can be a set of:
|
||||
<constant>a</constant> (<constant>A</constant> for directories),
|
||||
<constant>b</constant> (<constant>B</constant> for directories),
|
||||
<constant>c</constant> (<constant>C</constant> for directories; ignored by default), or
|
||||
<constant>m</constant> (<constant>M</constant> for directories),
|
||||
indicating access, creation, last status change, and last
|
||||
modification times of a file system entry respectively. See
|
||||
<citerefentry project='man-pages'><refentrytitle>statx</refentrytitle><manvolnum>2</manvolnum></citerefentry>
|

file timestamp fields for more details.</para>
|
||||
|
||||
<para>If unspecified, the age-by field defaults to
|
||||
<constant>abcmABM</constant>,
|
||||
i.e., by default all file timestamps are taken into consideration,
|
||||
with the exception of the last status change timestamp (ctime) for
|
||||
directories. This is because the aging logic itself will alter the
|
||||
ctime whenever it deletes a file inside it. To ensure that running
|
||||
the aging logic does not feed back into the next iteration of it,
|
||||
ctime for directories is ignored by default.</para>

|
||||
<para>For example:<programlisting>
|

# Files created and modified, and directories accessed more than
